2009-07-31Change av_log() calls surrounded by '#ifdef DEBUG' into dprintf macros.Diego Biurrun
Originally committed as revision 19550 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-07-04If the end of the input buffer is reached while decoding MJPEG and at leastReimar Döffinger
a valid SOF was found, emulate an EOI. This allows e.g. to at least decode the available part of incomplete MJPEG frames. Originally committed as revision 19344 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-07-04Make the MJPEG decoder return -1 when no image was decoded so that decodeReimar Döffinger
errors are actually recognizable as such. Originally committed as revision 19343 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-07-04Add a got_picture flag to MJpegDecodeContext which indicates if its pictureReimar Döffinger
element is valid. Skip the code handling SOS and EOI if not, since it can not work without a valid AVPicture. This fixes a crash with mjpeg/smclockmjpeg.avi.1.0 from issue 1240 where the decoder returned an invalid AVPicture. Originally committed as revision 19342 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-07-04mjpegdec: check that the coded dc_index and ac_index have a valid associated ↵Reimar Döffinger
VLC table. Removes some disabled dc_index/ac_index checking code that seems to have had some undocumented issues and should not really be necessary anymore now. Fixes from issue 1240 the files mjpeg/smclockmjpeg.avi.1.10 and mjpeg/smclockmjpeg.avi.1.171. Originally committed as revision 19341 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-05-25honor restart interval in mjpeg, fix #861, SpectralFan.mov still decodes ↵Baptiste Coudurier

2009-04-17Remove unused variables from ff_mjpeg_decode_sos() found by CSA.Michael Niedermayer
Originally committed as revision 18548 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-07Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann
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. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-02-01Use full internal pathname in doxygen @file directives.Diego Biurrun

2008-09-27Check the 4th plane too when selecting the pixfmt.Michael Niedermayer

2007-10-13Fix MJPEG decoder for AMV files.Vladimir Voroshilov
Since decoding is doing from the end and aligned by 16 previous code worked correctly only when picture height was dividable by 16, otherwise it provides garbage in top lines and truncates bottom. New code adjusts data[] pointers taking in account alignment issue. Originally committed as revision 10727 to svn://svn.ffmpeg.org/ffmpeg/trunk
