Thiago Santos e35085e5b5 qtdemux: Add more fields to SVQ3 caps 
qtdemux only added the whole stsd atom as 'codec_data'
in its output caps for SVQ3. This patch makes it add
the SEQH (inside a SMI atom) and a gamma field (taken
from the gama atom) if available.

Fixes #587922

Andy Wingo c917d65e6d qtdemux: unpack more information into image/x-j2c caps 
* gst/qtdemux/qtdemux_fourcc.h: Add new fourccs for use by the mj2
  unpacker.
* gst/qtdemux/qtdemux.c (qtdemux_parse_trak): Unpack JPEG2000 component
  mapping and channel definitions from the jp2h header. Will add
  component-map and channel-definitions elements to the caps if the
  component maps or channel definitions are nonstandard, where standard
  order means RGB, 444 packed YUV, or greyscale, with no alpha channel.

Fixes #598915.

Jan Schmidt 42b09362f6 qtdemux: Fix uninitialized variable warnings 
The gcc on the OS/X buildbot complains about these variables not being
initialized, even though they can't possibly actually be used
uninitialized.

Mark Nauwelaerts b2d70862e8 qtdemux: support 3GPP timed text subtitles

Tim-Philipp Müller 45ff905771 qtdemux: make sure compatible brands buffer exists before dereferencing it 2009-10-05 11:46:08 +01:00
Robert Swain c7b5df91a9 qtdemux: fix printf warnings on OSX 
Cast variables passed to printf to avoid warnings about incorrect
formats (most likely caused by sizeof returning a size_t).

Fixes #597348.

Tim-Philipp Müller 4590daf202 qtdemux: remove internal genre table 
No need to maintain our own genre table in qtdemux. The genres are
identical to the ID3 genres, so we can just use libgsttag's
gst_tag_id3_genre_get() to look them up.
 2009-10-05 00:26:44 +01:00
Mark Nauwelaerts 0fac7b5347 qtdemux: some optional QT specified stsd MPEG-4 atoms also apply to H264

Mark Nauwelaerts e21d16a4f8 qtdemux: only send tag events downstream after newsegment 2009-09-25 16:47:42 +02:00
Wim Taymans 03f46a42e5 qtdemux: add durations modulo 1<<32 
For calculating the durations of each sample, we are supposed to add each
duration modulo 1<<32 so make the elapsed time counter a uint32.

Fixes #595942

Wim Taymans 4e114a2b24 qtdemux: small cleanup 2009-09-24 20:38:54 +02:00
Tim-Philipp Müller 01e00ba1cd qtdemux: don't use core API that doesn't exist yet 
There's no gst_byte_reader_has_remaining() yet. Fixes build.

Tim-Philipp Müller fab4113c24 qtdemux: map some atomparser functions to their new bytereader equivalents 
Now that GstByteReader has unchecked and inlined variants as well, map
atomparser functions to their respective bytereader equivalents.

Tim-Philipp Müller 0f197776e1 qtdemux: add qt_atom_parser_has_chunks() and fix indentation 2009-09-24 16:32:02 +01:00
Tim-Philipp Müller f65e6ea3a1 qtdemux: bail out instead of trying to alloc silly index sizes 
If it looks like we would be allocating a silly size for our sample
index, just bail out instead of trying to allocate it. Helps with
broken or fuzzed files where we might end up trying to malloc a
couple of hundred MBs otherwise.

Tim-Philipp Müller abaf91e428 qtdemux: error out correctly if we don't even have enough bytes for an atom header 2009-09-24 16:29:25 +01:00

Tim-Philipp Müller 9da3ed6491 qtdemux: add qt_atom_parse_has_remaining() to avoid overflows with _get_remaining() 2009-09-24 16:28:40 +01:00
Tim-Philipp Müller a16feec38e qtdemux: use GstByteReader when parsing tkhd atom 2009-09-23 16:54:43 +01:00
Tim-Philipp Müller 6b7f4f5e23 qtdemux: use unsigned ints for node length and do more sanity checking of the atom length 2009-09-23 16:54:43 +01:00
Tim-Philipp Müller 3abeb1e578 qtdemux: use GstByteReader for atom dumping and fix a few bugs 2009-09-23 16:54:42 +01:00
Tim-Philipp Müller c8c9b0f35d qtdemux: move stco, stts, stss and stps atom parsing over to GstByteReader 
Make sure we don't read beyond the atom boundary. Note that the code
behaves slightly differently in the corner case where there is not
enough atom data for the specified number of samples (n_samples_time)
in the atom, but still enough data to fill the pre-allocated index of
n_samples entries: before we would just stop parsing the stts data
and continue, whereas now we will likely error out. This should not
be a problem in practice though. We could maintain the old behaviour
by doing reads with a size check inside the loop if needed.

Tim-Philipp Müller 4be46b1586 qtdemux: use bytereader to parse stsz and stsc atoms 
Use GstByteReader to parse stsz and stsc chunks, and check size of
available data before parsing it, instead of blindly assuming there
will be enough data. Fixes crashes with some fuzzed/broken files.
 2009-09-23 16:54:42 +01:00
Tim-Philipp Müller 5875e2016a qtdemux: add qt_atom_parser_get_offset() and optimise _peek_sub() 2009-09-23 16:54:42 +01:00
Tim-Philipp Müller 410ebb7eb3 qtdemux: add QtAtomParser, an inlined GstByteReader variant 2009-09-23 16:54:41 +01:00
