78ab2cdffd vc1parse: Fix compiler warnings when compiling with G_DISABLE_ASSERT 2014-06-29 20:11:58 +02:00

9bd186a960 codecparsers: h264: fix memory leak in GstH264PPS.
The gst_h264_parse_pps() function dynamically allocates the slice
group ids map array, so that needs to be cleared before parsing a
new PPS NAL unit again, or when it is no longer needed.

Likewise, a clean copy to the internal NAL parser state needs to be
performed so that to avoid a double-free corruption.

67df207280 codecparsers: h264: add support for Recovery Point SEI message.
The recovery point SEI message helps a decoder in determining if the
decoding process would produce acceptable pictures for display after
the decoder initiates random access or after the encoder indicates
a broken link in the coded video sequence.

This is not used in the h264parse element, but it could help debugging.

d9d4a91c62 h265parse: fix hvcC size check
In ISO/IEC 14496-15, the minimum size of a HEVCDecoderConfigurationRecord
(i.e., the contents of a hvcC box) is 23 bytes. However, the code in h265parse
checks that the size of this data is not less than 28 bytes, and it refuses to
accept caps if the check fails. The result is that standards-conformant streams
that don't carry any parameter sets in their hvcC boxes won't play.

4e283dbb62 mpeg4videoparse: do not lose DISCONT flag if buffer isn't pushed
mpeg4videoparse might not push buffers while parsing. If those buffers
contain the DISCONT flag, it gets lost and downstream won't get any
buffer with the flag.

Fix it by adding the DISCONT to the next pushed buffer.
This makes backwards playback work.

1b747bfecb h264parse: Fix splitting of multiple NALU per buffer
Conversion to byte-stream/nal crashes without that because the
baseparse frame of all NALUs is finished for the first NALU, then
used again for parsing the second NALU. Just that now the buffer
of the frame is already gone. Instead we create temporary frames
for every NALU.

31d1c05871 h264parse: Add support for stream-format=avc3
When outputting in AVC3 stream format, the codec_data should not
contain any SPS or PPS, because they are embedded inside the stream.

In case of avc->bytestream h264parse will push the SPS and PPS from
codec_data downstream at the start of the stream, at intervals
controlled by "config-interval" and when there is a codec_data change.

In the case of avc3->bytstream h264parse detects that there is
already SPS/PPS in the stream and sets h264parse->push_codec to FALSE.
Therefore avc3->bytstream was already supported, except for the stream
type.

In the case of bystream->avc h264parse will generate codec_data caps
from the parsed SPS/PPS in the stream. However it does not remove these
SPS/PPS from the stream. bytestream->avc3 is the same as bytestream->avc
except that the codec_data must not have any SPS/PPS in it.

|--------------+-------------+-------------------|
|stream-format | SPS in-band | SPS in codec_data |
|--------------+-------------+-------------------|
| avc          | maybe       | always            |
|--------------+-------------+-------------------|
| avc3         | always      | never             |
|--------------+-------------+-------------------|

Amendment 2 of ISO/IEC 14496-15 (AVC file format) is defining a new
structure for fragmented MP4 called "avc3". The principal difference
between AVC1 and AVC3 is the location of the codec initialisation
data (e.g. SPS, PPS). In AVC1 this data is placed in the initial MOOV box
(moov.trak.mdia.minf.stbl.stsd.avc1) but in AVC3 this data goes in the
first sample of every fragment.
