wm4	921706691a	qpeg: avoid pointless invalid memcpy() If refdata was NULL, the memcpy() ended up copying the same memory block onto itself, which is not only pointless, but also undefined behavior. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	dd3bfe3cc1	avcodec/qpeg: fix off by 1 error in MV bounds check Fixes out of array access Fixes: asan_heap-oob_153760f_4_asan_heap-oob_1d7a4cf_164_VWbig6.avi Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	f13f139feb	avcodec/qpeg: make qpeg_decode_inter() noinline This should workaround an apparent mis-compilation with gcc 4.2 on BSD The function is rarely called and not inlining should have no speed effect Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Aneesh Dogra	3e9cd8b4b0	qpeg: Use bytestream2 functions to prevent buffer overreads. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Michael Niedermayer	81d4b3af81	qpeg: fix overreads. qpeg should probably be changed to use the checked bytestream reader. But for now this fixes it and is significantly less work.

Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
Stefano Sabatini	01042d4123	lavc: set defaults in internal codec frames This is required specifically for setting frame->format to -1, otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading the format from the output decoded frame will get misled. In particular fix regressions occurring with the pending vsrc_buffer patch.	14 years ago

Michael Niedermayer	90bcbc791f	Revert "qpeg: use reget_buffer() in decode_frame()" This reverts commit `f4e043ff63`.	14 years ago
Stefano Sabatini	f4e043ff63	qpeg: use reget_buffer() in decode_frame() Decoder relies on previous frame data, so use reget_buffer(). This also set frame->reference to 3, as the frame will be requested unmodified later so it shouldn't be modified by the application. Fix playback of file Clock.avi. Signed-off-by: Ronald S.

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	5be5daf1e5	Check that palctrl is available on init instead of crashing when trying to use it on decode. Fixes mpeg2/smclockmpeg2.avi.2.1 from issue 1240. Originally committed as revision 19347 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Kostya Shishkov	1c86db80a9	Remove useless assignment during initialization for some decoders Originally committed as revision 18680 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist.
