Vitaliy E Sugrobov	005cb97e3e	Move some definitions to header file. Share them with upcoming demuxer module. Signed-off-by: Vitaliy E Sugrobov <vsugrob@hotmail.com>	12 years ago
Vitaliy E Sugrobov	de0cb7f070	Additional checks to prevent overread. Check for availability of some required amount of bytes in buffer before reading further. Signed-off-by: Vitaliy E Sugrobov <vsugrob@hotmail.com>	12 years ago
Vitaliy E Sugrobov	91499f4ee8	Prepare gif decoder for use in conjunction with gif demuxer. Add capability of reading multiple frames instead of only first. Implement support for different gif frame 'disposal methods'. Add option that allows to change background color resulting from conversion of gif with transparency to any other format which not support it. Also bump lavc minor version.

Vitaliy E Sugrobov	c5fe41c768	Add meaningful error codes and constants. Replace literals with named constants in several pieces of code like 'return -1' and 'case 0xab'. Change the way decoder handles absence of image data in a file: notify gif_decode_frame() caller with got_picture set to zero instead of returning -1.

Michael Niedermayer	a2f680c7bc	mjpegdec: check h/v_count, fix context becoming inconsistent and causing out of array accesses. This also fixes a long standing comment in the code.

Stefano Sabatini	08d0969c14	lavu/opt: change the way default pixel and sample format value is set Use the i64 field rather than the string value. Using a string to set a default sample/pixel format is weird, also the new interface is more consistent with the rest of the API. This is technically an API break, but hopefully there are no applications using this feature outside of FFmpeg. In order to save backward compatibility with mixed libraries in case libavutil is updated but not the other libraries, some ifdeffery hacks are added. Note that the version check is only performed when class->version != 0, since if it is not defined then we assume that no version was defined and the class is not affected by the change. We will luckily get rid of the hack at the next major bump.	12 years ago

Reimar Döffinger	8aa29f063c	atrac3: do not use init_static_data to init VLC data. It would be called while registering the codec, which means it needlessly wastes memory when it is never used.

Janne Grunau	d5e83122bd	h264: set Picture.owner2 to the current thread This does not seem to have an effect currently. Fate-h264 passes with THREADS=1..16 and both threading types as before. It fixes however a segfault during error resilience with my adaptive-frame-mt patchset. A picture in use during error resilience gets realloced in another thread in the fuzzed sample sample_varPAR.avi_s226019.	12 years ago

Michael Niedermayer	5d47850bbd	dcadec: skip QMF on unused channels When the extra rear channel is present but unused, the s->channel_order_tab[] value for that channel is -1. The QMF can be skipped for the extra channel, and doing so avoids an out-of-array read on s->samples_chanptr[].
