dashdemux: add support for generating Protection events from ContentProtection elements If a ContentProtection element is present in an AdaptationSet element, send Protection events on the source pad, so that qtdemux can use this information to correctly generate its source caps for DASH CENC encrypted streams. This allows qtdemux to support CENC encrypted DASH streams where the content protection specific information is carried in the MPD file rather than in pssh boxes in the initialisation segments. This commit adds a new function to the adaptivedemux base class to allow a GstEvent to be queued for a stream. The queue of events are sent the next time a buffer is pushed for that stream. https://bugzilla.gnome.org/show_bug.cgi?id=705991

dashdemux: add support for UTCTiming elements for clock drift compensation Unless the DASH client can compensate for the difference between its clock and the clock used by the server, the client might request fragments that either not yet on the server or fragments that have already been expired from the server. This is an issue because these requests can propagate all the way back to the origin ISO/IEC 23009-1:2014/Amd 1 [PDAM1] defines a new UTCTiming element to allow a DASH client to track the clock used by the server generating the DASH stream. Multiple UTCTiming elements might be present, to indicate support for multiple methods of UTC time gathering. Each element can contain a white space separated list of URLs that can be contacted to discover the UTC time from the server's perspective. This commit provides parsing of UTCTiming elements, unit tests of this parsing and a function to poll a time server. This function supports the following methods: urn:mpeg:dash:utc:ntp:2014 urn:mpeg:dash:utc:http-xsdate:2014 urn:mpeg:dash:utc:http-iso:2014 urn:mpeg:dash:utc:http-ntp:2014 The manifest update task is used to poll the clock time server, to save having to create a new thread. When choosing the starting fragment number and when waiting for a fragment to become available, the difference between the server's idea of UTC and the client's idea of UTC is taken into account. For example, if the server's time is behind the client's idea of UTC, we wait for longer before requesting a fragment [PDAM1]: http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=66068 dashdemux: support NTP time servers in UTCTiming elements Use the gst_ntp_clock to support the use of an NTP server. https://bugzilla.gnome.org/show_bug.cgi?id=752413

dashdemux: Change first fragment selection for live streams When dashdemux selects its first fragment, it always selects the first fragment listed in the manifest. For on-demand content, this is the correct behaviour. However for live content, this behaviour is undesirable because the first fragment listed in the manifest might be some considerable time behind "now". The commit uses the host's idea of UTC and tries to find the oldest fragment that contains samples for this time of day. https://bugzilla.gnome.org/show_bug.cgi?id=701509

dashdemux: add support for UTCTiming elements for clock drift compensation Unless the DASH client can compensate for the difference between its clock and the clock used by the server, the client might request fragments that either not yet on the server or fragments that have already been expired from the server. This is an issue because these requests can propagate all the way back to the origin ISO/IEC 23009-1:2014/Amd 1 [PDAM1] defines a new UTCTiming element to allow a DASH client to track the clock used by the server generating the DASH stream. Multiple UTCTiming elements might be present, to indicate support for multiple methods of UTC time gathering. Each element can contain a white space separated list of URLs that can be contacted to discover the UTC time from the server's perspective. This commit provides parsing of UTCTiming elements, unit tests of this parsing and a function to poll a time server. This function supports the following methods: urn:mpeg:dash:utc:ntp:2014 urn:mpeg:dash:utc:http-xsdate:2014 urn:mpeg:dash:utc:http-iso:2014 urn:mpeg:dash:utc:http-ntp:2014 The manifest update task is used to poll the clock time server, to save having to create a new thread. When choosing the starting fragment number and when waiting for a fragment to become available, the difference between the server's idea of UTC and the client's idea of UTC is taken into account. For example, if the server's time is behind the client's idea of UTC, we wait for longer before requesting a fragment [PDAM1]: http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=66068 dashdemux: support NTP time servers in UTCTiming elements Use the gst_ntp_clock to support the use of an NTP server. https://bugzilla.gnome.org/show_bug.cgi?id=752413

Replaces the processed media segments GList for a GPtrArray as it is constantly acessed by index during playback.

dashdemux: add support for UTCTiming elements for clock drift compensation Unless the DASH client can compensate for the difference between its clock and the clock used by the server, the client might request fragments that either not yet on the server or fragments that have already been expired from the server. This is an issue because these requests can propagate all the way back to the origin ISO/IEC 23009-1:2014/Amd 1 [PDAM1] defines a new UTCTiming element to allow a DASH client to track the clock used by the server generating the DASH stream. Multiple UTCTiming elements might be present, to indicate support for multiple methods of UTC time gathering. Each element can contain a white space separated list of URLs that can be contacted to discover the UTC time from the server's perspective. This commit provides parsing of UTCTiming elements, unit tests of this parsing and a function to poll a time server. This function supports the following methods: urn:mpeg:dash:utc:ntp:2014 urn:mpeg:dash:utc:http-xsdate:2014 urn:mpeg:dash:utc:http-iso:2014 urn:mpeg:dash:utc:http-ntp:2014 The manifest update task is used to poll the clock time server, to save having to create a new thread. When choosing the starting fragment number and when waiting for a fragment to become available, the difference between the server's idea of UTC and the client's idea of UTC is taken into account. For example, if the server's time is behind the client's idea of UTC, we wait for longer before requesting a fragment [PDAM1]: http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=66068 dashdemux: support NTP time servers in UTCTiming elements Use the gst_ntp_clock to support the use of an NTP server. https://bugzilla.gnome.org/show_bug.cgi?id=752413

dashdemux: improve validation of UTCtiming element gst_mpdparser_parse_utctiming_node does not validate the parsed values completely. The following scenarios are incorrectly accepted: - elements with no schemeIdUri property should be rejected - elements with unrecognized UTCTiming scheme should be rejected - elements with empty values should be rejected The last one triggers a division by 0 in gst_dash_demux_poll_clock_drift: clock_drift->selected_url = clock_drift->selected_url % g_strv_length (urls); because it urls is a valid pointer to an empty array. https://bugzilla.gnome.org/show_bug.cgi?id=759547

dashdemux: add support for UTCTiming elements for clock drift compensation Unless the DASH client can compensate for the difference between its clock and the clock used by the server, the client might request fragments that either not yet on the server or fragments that have already been expired from the server. This is an issue because these requests can propagate all the way back to the origin ISO/IEC 23009-1:2014/Amd 1 [PDAM1] defines a new UTCTiming element to allow a DASH client to track the clock used by the server generating the DASH stream. Multiple UTCTiming elements might be present, to indicate support for multiple methods of UTC time gathering. Each element can contain a white space separated list of URLs that can be contacted to discover the UTC time from the server's perspective. This commit provides parsing of UTCTiming elements, unit tests of this parsing and a function to poll a time server. This function supports the following methods: urn:mpeg:dash:utc:ntp:2014 urn:mpeg:dash:utc:http-xsdate:2014 urn:mpeg:dash:utc:http-iso:2014 urn:mpeg:dash:utc:http-ntp:2014 The manifest update task is used to poll the clock time server, to save having to create a new thread. When choosing the starting fragment number and when waiting for a fragment to become available, the difference between the server's idea of UTC and the client's idea of UTC is taken into account. For example, if the server's time is behind the client's idea of UTC, we wait for longer before requesting a fragment [PDAM1]: http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=66068 dashdemux: support NTP time servers in UTCTiming elements Use the gst_ntp_clock to support the use of an NTP server. https://bugzilla.gnome.org/show_bug.cgi?id=752413

Corrected gst_mpdparser_get_rep_idx_with_max_bandwidth function to get the correct representation in case max_bandwidth parameter is 0. https://bugzilla.gnome.org/show_bug.cgi?id=751153

dashdemux: add support for UTCTiming elements for clock drift compensation Unless the DASH client can compensate for the difference between its clock and the clock used by the server, the client might request fragments that either not yet on the server or fragments that have already been expired from the server. This is an issue because these requests can propagate all the way back to the origin ISO/IEC 23009-1:2014/Amd 1 [PDAM1] defines a new UTCTiming element to allow a DASH client to track the clock used by the server generating the DASH stream. Multiple UTCTiming elements might be present, to indicate support for multiple methods of UTC time gathering. Each element can contain a white space separated list of URLs that can be contacted to discover the UTC time from the server's perspective. This commit provides parsing of UTCTiming elements, unit tests of this parsing and a function to poll a time server. This function supports the following methods: urn:mpeg:dash:utc:ntp:2014 urn:mpeg:dash:utc:http-xsdate:2014 urn:mpeg:dash:utc:http-iso:2014 urn:mpeg:dash:utc:http-ntp:2014 The manifest update task is used to poll the clock time server, to save having to create a new thread. When choosing the starting fragment number and when waiting for a fragment to become available, the difference between the server's idea of UTC and the client's idea of UTC is taken into account. For example, if the server's time is behind the client's idea of UTC, we wait for longer before requesting a fragment [PDAM1]: http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=66068 dashdemux: support NTP time servers in UTCTiming elements Use the gst_ntp_clock to support the use of an NTP server. https://bugzilla.gnome.org/show_bug.cgi?id=752413

dashdemux: add support for UTCTiming elements for clock drift compensation Unless the DASH client can compensate for the difference between its clock and the clock used by the server, the client might request fragments that either not yet on the server or fragments that have already been expired from the server. This is an issue because these requests can propagate all the way back to the origin ISO/IEC 23009-1:2014/Amd 1 [PDAM1] defines a new UTCTiming element to allow a DASH client to track the clock used by the server generating the DASH stream. Multiple UTCTiming elements might be present, to indicate support for multiple methods of UTC time gathering. Each element can contain a white space separated list of URLs that can be contacted to discover the UTC time from the server's perspective. This commit provides parsing of UTCTiming elements, unit tests of this parsing and a function to poll a time server. This function supports the following methods: urn:mpeg:dash:utc:ntp:2014 urn:mpeg:dash:utc:http-xsdate:2014 urn:mpeg:dash:utc:http-iso:2014 urn:mpeg:dash:utc:http-ntp:2014 The manifest update task is used to poll the clock time server, to save having to create a new thread. When choosing the starting fragment number and when waiting for a fragment to become available, the difference between the server's idea of UTC and the client's idea of UTC is taken into account. For example, if the server's time is behind the client's idea of UTC, we wait for longer before requesting a fragment [PDAM1]: http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=66068 dashdemux: support NTP time servers in UTCTiming elements Use the gst_ntp_clock to support the use of an NTP server. https://bugzilla.gnome.org/show_bug.cgi?id=752413

dashdemux: stop fetching live fragments that don't yet exist There is an issue for live streams where download_loop will keep downloading segments until it gets a 404 error for a segment that has not yet been published. This is a problem because this request for a segment that doesn't exist will propagate all the way back to the origin server(s). This means that dashdemux causes extra load on the origin server(s) for segments that aren't yet available. This patch uses availabilityStartTime, period and the host's idea of UTC to decide if a fragment is available to be requested from an HTTP server and filter out requests for fragments that are not yet available. https://bugzilla.gnome.org/show_bug.cgi?id=701404

When deallocating GLists, there were many places that were using g_list_foreach and g_list_free. Converted these occurrences to call g_list_free_full. Add NULL checks to all xmlFree calls since the documentation does not guarantee that passing NULL is safe In places where we are strdup'ing memory allocated by libxml2, changed those calls to use xmlMemStrdup(). There were several places where we were missing g_slice_free when deallocating a top-level node structure. https://bugzilla.gnome.org/show_bug.cgi?id=702837

Snap seeking in this case will be done in 2 steps: 1) do the snap seeking on the pad that received the seek event and get the final position 2) use this position to do a regular seek on the other streams to make sure they all start from the same position More arguments were added to the stream_seek function, allowing better control of how seeking is done. Knowing the flags and the playback direction allows subclasses to handle snap-seeking. And also adds a new return parameter to inform of the final selected seeking position that is used to align the other streams. https://bugzilla.gnome.org/show_bug.cgi?id=759158

dashdemux: Improve live stream manifest update repositioning When updating the manifest the timestamps on it might have changed a little due to rounding and timescale conversions. If the change makes the timestamp of the current segment to go up it makes dashdemux reposition to the previous one causing one extra unnecessary download. So when repositioning add an extra 10 microseconds to cover for that rounding issues and increase the chance of falling in the same segment. Additionally, also improve the time used when the client is already after the last segment. Instead of using the last segment starting timestamp use the final timestamp to make it reposition to the next one and not to the one that has already been downloaded.

dashdemux: add support for UTCTiming elements for clock drift compensation Unless the DASH client can compensate for the difference between its clock and the clock used by the server, the client might request fragments that either not yet on the server or fragments that have already been expired from the server. This is an issue because these requests can propagate all the way back to the origin ISO/IEC 23009-1:2014/Amd 1 [PDAM1] defines a new UTCTiming element to allow a DASH client to track the clock used by the server generating the DASH stream. Multiple UTCTiming elements might be present, to indicate support for multiple methods of UTC time gathering. Each element can contain a white space separated list of URLs that can be contacted to discover the UTC time from the server's perspective. This commit provides parsing of UTCTiming elements, unit tests of this parsing and a function to poll a time server. This function supports the following methods: urn:mpeg:dash:utc:ntp:2014 urn:mpeg:dash:utc:http-xsdate:2014 urn:mpeg:dash:utc:http-iso:2014 urn:mpeg:dash:utc:http-ntp:2014 The manifest update task is used to poll the clock time server, to save having to create a new thread. When choosing the starting fragment number and when waiting for a fragment to become available, the difference between the server's idea of UTC and the client's idea of UTC is taken into account. For example, if the server's time is behind the client's idea of UTC, we wait for longer before requesting a fragment [PDAM1]: http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=66068 dashdemux: support NTP time servers in UTCTiming elements Use the gst_ntp_clock to support the use of an NTP server. https://bugzilla.gnome.org/show_bug.cgi?id=752413

dashdemux: reworked the API to retrieve fragment timestamp, fragment duration and media presentation duration This was necessary to support variable-duration Fragments. in the new API: - gst_mpd_client_get_current_position returns the timestamp of the NEXT fragment to download; - gst_mpd_client_get_next_fragment_duration returns the duration of the next fragment to download; - gst_mpd_client_get_media_presentation_duration returns the mediaPresentationDuration from the MPD file; also there is a new internal parser function: - gst_mpd_client_get_segment_duration extracts the constant segment duration from the MPD file (only used when there is no SegmentTimeline syntax element in the current representation) In gst_mpd_client_get_next_fragment, we set the timestamp/duration of the fragment just downloaded copying the values from the corresponding GstMediaSegment.

dashdemux: Change first fragment selection for live streams When dashdemux selects its first fragment, it always selects the first fragment listed in the manifest. For on-demand content, this is the correct behaviour. However for live content, this behaviour is undesirable because the first fragment listed in the manifest might be some considerable time behind "now". The commit uses the host's idea of UTC and tries to find the oldest fragment that contains samples for this time of day. https://bugzilla.gnome.org/show_bug.cgi?id=701509

dashdemux: fix template based segment generation When using a template based segment list, do not try to contruct a finite segment list for the limits of the available periods. We might not know when the period ends (for live streams) and we can always create the segment on demand when requested by dashdemux, avoiding use of some memory and cpu when re-creating this list.

dashdemux: reimplementing live streams manifest updates Manifest updates should be done periodically for live streams, this patch makes the demuxer create a new manifest client for the new version and transfers the stream position to the new one, discarding the old one afterwards.

dashdemux: stop fetching live fragments that don't yet exist There is an issue for live streams where download_loop will keep downloading segments until it gets a 404 error for a segment that has not yet been published. This is a problem because this request for a segment that doesn't exist will propagate all the way back to the origin server(s). This means that dashdemux causes extra load on the origin server(s) for segments that aren't yet available. This patch uses availabilityStartTime, period and the host's idea of UTC to decide if a fragment is available to be requested from an HTTP server and filter out requests for fragments that are not yet available. https://bugzilla.gnome.org/show_bug.cgi?id=701404

mpdparser: renamed gst_mpd_client_get_next_segment_availability_end_time to gst_mpd_client_get_next_segment_availability_start_time The function actually returns the segment availability start time (as defined by the standard). That is at the end of the segment, but it is called availability start time. Availability end time is something else (the time when the segment is no longer available on the server). The function name was misleading. https://bugzilla.gnome.org/show_bug.cgi?id=757655

adaptivedemux: handle snap seeks Adaptive demuxers need to start downloading from specific positions (fragments) for every stream, this means that all streams can snap-seek to a different position when requested. Snap seeking in this case will be done in 2 steps: 1) do the snap seeking on the pad that received the seek event and get the final position 2) use this position to do a regular seek on the other streams to make sure they all start from the same position More arguments were added to the stream_seek function, allowing better control of how seeking is done. Knowing the flags and the playback direction allows subclasses to handle snap-seeking. And also adds a new return parameter to inform of the final selected seeking position that is used to align the other streams. https://bugzilla.gnome.org/show_bug.cgi?id=759158

dashdemux: provide a default suggestedPresentationDelay If MPD@suggestedPresentationDelay is not present in the manifest, dashdemux selects the fragment closest to the most recently generated fragment. This causes a playback issue because this choice does not allow the DASH client to build up any buffer of downloaded fragments without pausing playback. This is because by definition new fragments appear on the server in real-time (e.g. if segment duration is 4 seconds, a new fragment will appear on the server every 4 seconds). If the starting playback position was n*segmentDuration seconds behind "now", the DASH client could download up to 'n' fragments faster than realtime before it reached the point where it needed to wait for fragments to appear on the server. The MPD@suggestedPresentationDelay attribute allows a content publisher to provide a suggested starting position that is behind the current "live" position. If the MPD@suggestedPresentationDelay attribute is not present, provide a suitable default value as a property of the dashdemux element. To allow the default presentation delay to be specified either using fragments or seconds, the property is a string that contains a number and a unit (e.g. "10 seconds", "4 fragments", "2500ms").
