Alex Converse	4fab662769	AAC: Add a global header but output not locked output configuration status. Originally committed as revision 20701 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	38610d92ff	Set the SBR mode to implicit on ADTS frames occurring before the output is locked. Originally committed as revision 20700 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Mike Melanson	9d8bb0318a	Small refactoring: Instead of 4 loops for decoding AC coefficients based on their grouping, create one loop that indexes into a table of AC VLC tables. There is also a small optimization here: Do not call unpack_vlcs() if there are no fragments in the list with outstanding coefficients. My profiling indicates that this can save upwards of 1 million dezicycles per frame throughout the course of unpack_dct_coeffs(). Originally committed as revision 20699 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Mike Melanson	098523eb28	Use a list to track which fragments coded in this frame still have outstanding coefficients yet to be decoded from the bitstream. Once a fragment reaches end-of-block, remove it from this new list. This change makes the VP3/Theora entropy decode process dramatically faster due to not having to iterate incessantly over fragments which have already been fully decoded.

Michael Niedermayer	94f28061f5	Store original width/height so that rv20 does not get stuck with some resolution. A sample file to show a difference is at issue833 (http://airfarce.com/video/000211fh.rm) Originally committed as revision 20691 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	52069c4d3c	Move "slice below image" check from mpeg_decode_slice to its caller. Should fix issue1277. Originally committed as revision 20676 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	d52b4abe8b	Move dummy picture allocation code from mpeg1/2 to mpegvideo. This fixes a infinite loop on a b frame. Originally committed as revision 20672 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	fd1ef13bb4	Disable error resilience for field pictures, this was never supported, results where more or less random but should not have crashed. Originally committed as revision 20671 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	078cdecf9e	Set mb_y in mpeg2 field pictures like h264 does. This fixes -vismv & -debug 16384 with field pictures. Originally committed as revision 20670 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	22d4f21331	Make ""MPEG motion vector out of boundary" message more verbose. Originally committed as revision 20669 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Attila Kinali	76c4a644ee	Fix an issue uncovered by commit 20623: The init functions of mpc7 and mpc8 check whether the vlc has been initialized already and return early if this is the case (eg by calling init a second time). But avctx->sample_fmt and channel_layout is set after the vlc initialization, causing it not to be set on the second call of init. Move all manipulations of avctx before the initialization of the vlc, so that it is always set. Originally committed as revision 20668 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	ab8c48de8c	Start decoding from seq/gop too, not just I frames. Possibly fixes issue1124. Originally committed as revision 20667 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Reimar Döffinger	7c7d3abf3c	10l, pix_fmt should be set by the motionpixels decoder, not by the demuxer. This fixes playback when lavf and lavc are less tightly couples as in e.g. MPlayer. Originally committed as revision 20626 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	797229a6a2	Make avcodec_get_pix_fmt_name() use av_pix_fmt_descriptors rather than pix_fmt_info. Originally committed as revision 20625 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jai Menon	0bf095a837	Allow decoders to correctly set the sample format by defaulting to SAMPLE_FMT_NONE in avcodec_get_context_defaults2. Originally committed as revision 20623 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
