This simply implies not trying to "prepare" those buffers,
as mapping an empty buffer to a video frame does not make
much sense.
This also adds a simple test in compositor that performs
some trivial checking of the handling of gap events, the test
was not failing before, but an error was logged, this is
no longer the case.
Fixes#717
If there's no known value in the best caps then the functions to convert
them to strings will return NULL. Having the fields not in the caps is
not a problem, having them with a NULL value however will cause
negotiation failures.
The main_input stream-id would not get reset when going to READY state.
This would cause warnings when trying to reuse the same decodebin3, since
you would get a new STREAM_START event with a new stream-id, which would
collide with the now stale stream-id
Fixes regression introduced by "clean-up" done as part of commit 98ebcb4.
dummy must live as long as use the return value of localtime_r() since
that's just a pointer to it, and by putting it inside the block we made
dummy go out of scope right after localtime_r() returned, which messed
up the time values since when we poked at the struct the contents might
already have been overwritten.
Fixes#722
The default values were not being set on element initialization. This
was a problem for buffer_duration and buffer_size since they would be
zero initialized, rather then being set to -1. This would cause the
underlaying queue2 element to have no limits and depending on the
streamed file, could cause queue2 to allocate massive amounts of memory.
This validate that the base class properly save and return the flow
return value received when gst_rtp_base_depay_push/push_list() helper is
being used.
Save push/push_list helper flow return and in case of failure, return it
in the process function. This allow forwarding downstream flow return
even if the subclass is using the push/push_list helper.
In decodebin3 and uridecodebin3 the `force-sw-decoders` boolean property is
added. In uridecodebin3 it is only a proxy property which will forward
the value to decodebin3.
When decodebin3 has `force-sw-decoders` disabled, it will filter out in its
decoder and decodable factories those elements within the 'Hardware'
class, at reconfiguring output stream.
playbin3 adds by default GST_PLAY_FLAG_FORCE_SW_DECODERS, and sets
`force-sw-decoders` property accordingly to its internal uridecodebin, also
filters out the 'Hardware' class decoder elements when caps
negotiation.
Added `force-sw-decoders` boolean property in decodebin2 and
uridecodebin. By default the property is %FALSE and it bypass the new
code. Otherwise the factory list is filtered removing decoders
within 'Hardware' class.
uridecodebin sets the `force-sw-decoders` property in its internal
decodebin, and also filters out Hardware class in the
autoplug-factories default signal handler.
playbin2 adds by default GST_PLAY_FLAG_FORCE_SW_DECODERS it its flags
property, and depending on it playbin2 sets the `force-sw-decoders`
property on its internal uridecodebin, also filters out the Hardware
class decoding decoders at the autoplug-factories signal handler.
When the playsink's sink is activated its state is set to READY but it remains
unlinked. So, in order for decodebin3 to potentially reuse the context later on,
the whole playbin3 needs to have it internally stored.
In prepare_frame, it is not enough for the target info
(conversion_info) to not have changed to decide not to update
the converter, as the vpad info may have changed as well.
Fixes#714
Posting any message to parent seems to be pointless. That might break
parent window.
Regardless of the posting, parent window can catch mouse event
and also any keyboard events will be handled by parent window by default.

This marker is optional, its name refer to RTP marker bit. This mark can
be use to reduce latency in various use cases. With the split between
finish_frame() and finish_subframe() we will now be able to identitfy
the last subframe with no latency.
In order to detail the use of GST_BUFFER_FLAG_MARKER in a video
use case, the flag GST_VIDEO_BUFFER_FLAG_MARKER has been introduced
with a proper documentation clarifying marker's role.
Introduce a new API so encoders can split the encoding in subframes.
This can be useful to reduce the overall latency as we no longer need to
wait for the full frame to be encoded to start decoding or sending it.
This is not set anywhere, and it's pretty clear the pipeline in
question has not been tested in a long time. Disable test with
a FIXME, test needs to be rewritten to not use real output devices.
