Remove the android/ top dir
Fixe the Makefile.am to be androgenized
To build gstreamer for android we are now using androgenizer which generates the needed Android.mk files.
Androgenizer can be found here: http://git.collabora.co.uk/?p=user/derek/androgenizer.git
Or possibly even at startup. If we couldn't find a sync within
the first few bytes, we'd just push more data into the adapter
but never discard any of the invalid data at the beginning, so
would never be able to re-sync.

<tpm> leio, what's the mpegts demux hack about?
<leio> my libdvbsub code can't handle cut packets
<leio> so the hack instructs the demuxer to gather full packets before pushing down, but it applies that to more PES packet types than just dvbsub, but I'm not sure if that's a bad thing
<leio> either way, needs a cleaner solution, either in demuxer, or I need to handle cut packets
<tpm> ok, but really it should be fixed in the overlay, right?
<tpm> or a parser be inserted
<leio> the problem is that I don't know from the first packet beforehand if it is a cut one or no
<leio> not
<leio> err, first buffer
<leio> just when I receive the next one I see if it has a valid timestamp on it or not
<leio> so I can't very well queue it up in the chain either, I might be blocking the very last subtitle for no reason or something
<tpm> but you could just drop/ignore packets until you find one, right?
<leio> find what?
<tpm> a complete packet?
<leio> the problem isn't that they aren't complete
<leio> the problem is that they are cut across multiple GstBuffers by the demuxer without the hack
<tpm> sure, I understand that
<tpm> but you can't easily determine if a GstBuffer contains he start fragment of a packet or not?
<leio> I guess I could parse the packet and see if its length is enough, just like the libdvbsub code eventually does too
<leio> I can, it has a timestamp if it's the first chunk
<leio> I just never know if I need to wait for more, without some parsing
<tpm> ah ok
<leio> while the demuxer could just give me an uncut one in the first place
<leio> like it always does for program streams
<leio> that gather_pes is always set in gstmpegdemux, but not in gstmpegtsdemux
TDT and TOT sections, with PID=0x14, doesn't extend to several packets
and the section filter is not needed here and shouldn't be used at all
for these tables because the have a different structure.
For example, TDT tables were not parsed for odd hours because this bit
is the 'current_next_indicator' bit for the other sections, and the table
was discarded.
This is a problem if you tune to a channel which uses pid X and later tune to
another channel where X is used for another table (e.g. PMT).
The code that does that was actually already there but never used because the
pat structure was freed before. The commit that introduced those lines intended
to fix a memory leak, but we clean things up elsewhere.
Fixes#622725.
gst_mpeg_descriptor_find() expects the description field to be non-NULL.
This fixes a couple of calls where the value being passed is not
verified to be non-NULL first.

Some tables in MPEG-TS do not have a crc in the spec, so also mpegtsparse
is not calculating crc for sections with table_id 0x70 - 0x72 because they
do not have a CRC in the spec. See EN300468. Parse Time and Date table and
output bus message.
gcc 4.5 warns when comparing some integer with an enum value, in
the case of GstFlowReturn this is valid though. We should later
add GST_FLOW_CUSTOM_OK1, GST_FLOW_CUSTOM_OK2, etc. after new core
is released.
The current code just uses table id, subtable extension and version number to
check if the section has been seen before. However, this comparison is not
sufficient, causing actually new tables being dismissed.
Fixes bug #614479.
Because config.h defines __MSVCRT_VERSION__, which should be defined
before inclusion of any system header.
Also fixes mpegdemux Makefile.am LIBADD typo.
Fixes#606665
When the stream type is set to private data, gst-mpegtsdemux is trying to find
audio descriptors in PMT and look for AC3 (tag 0x6a) but doesn't look for EAC3
(tag 0x7a). Handle this case too.
Fixes bug #605904.
There is unfortunately no G_*_FORMAT conversion specifier for differences of
pointers in glib, and we can't rely either on all platforms being 64bit.
So let's just cast the difference to a gint and be done with it.
When sending new-segment to a stream, ensure that there is either a valid
PCR, or else wait until there's a PTS on the stream (dropping packets if
needed) in order to avoid generating an invlaid new-segments event.

Using a GstIterator is slow because we have to create/destroy that
iterator every single time.
We just do the threadsafe cookie check and list iteration ourselves.
There's no need for an extra function since all debuggin will require
a MpegTSPacketizer which means that the GType will be created, therefore
move the debug category initialization there.
This fixes naive seeking a tiny bit (by basically hinting at _data_cb
that it shouldn't expect the incoming buffers to be the ones just after
the previous ones).
Without this, seeking by more than 10mins forward would just end up in an
endless loop.
This attribute can't be used for function declarations because
it needs the function body. Instead of a forward declaration of
functions, move the function itself above it's first use.
Fixes bug #594489 and compilation with gcc 4.3 and earlier.
In the clips that I've found those streams, the lpcm header is
different than the DVD case.
Then the decoder need to know this in order to be able parse it.
Increased performance doing pull_range in blocks of 32Kb instead of 4Kb.
Caching the value of gst_adapter_available instead of calling it 3 times.
Added some comments with the header descriptions.
Peek enough data to avoid a corner case where could be readed data outside
the buffer.
Speed up some more inlining some functions and keeping another stream pointer
list to be used as iterator.
Sprinkle branch prediction macros accross the code.
Handling the seeking with flush in pull mode in the proper way.
If there is an ISO 639 language descriptor for a stream, send a language
code tag so that players can show a meaningful language for the audio and
subtitle streams.
Don't treat some streams (Private Stream 2) as LPCM when they're not. Fixes
playback of files that have private streams in them now that the PES filter
emits such packets.
If the estimated bitrate is lower than 188 bytes, there's most likely
something completely wrong with the two samples. If that happens,
force recalculation.
Use guint64 for observation PCR, I saw cases where it would overflow.
This allows debugging with mpegtsdemux:4 while being able to track what's
going on (and avoid taking up as much cpu for debugging as for the actual
demuxing process).
Sync from gst-fluendo-mpegdemux and have seeking/duration query
improvements in. No support however for wrapped around pcrs etc. but a
start nonetheless.
Also fix indentation issues.
This should remove the bogus error messages while still keeping the original
intent of this, which is to inform the pipeline/application/user that we
could not find any valid streams.
There are many reasons why pushing an event can fail, and not all of them are
because there's no link downstream (it could be because it was blocked, or
flushing).
itvhd masks its h264 video stream as a private stream making it harder for
other set top boxes to decode. this checks for specific program number, video
pid and stream type combination before declaring it as h264.
don't ignore the return value of pull_range because we only get a valid non-NULL
buffer when the return value is GST_FLOW_OK. Avoids a crash when the pipeline is
shutting down.
