Michael Niedermayer	2dec950f49	avcodec_open: if obtaining a lock fails, dont attempt to unlock it. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	0393cf15db	Revert "Acquire lock when initializing parsers." This reverts commit `7feef7dbca`. This commit causes assertion failures due to use of parser_init from multiple threads, for example indirectly by ffmpeg.c and more directly from the packet read functions. I dont know how to fix this quickly, and fixing ffmpeg.c leaves the possibility of other applications being affected. Crashing the applications until this is resolved is clearly no good thus this revert, so we have time to think about the problem. Crashes can be reproduced by using multiple input files in ffmpeg.	12 years ago

Nicolas George	217b10de3f	lavc/dvdsubdec: accept palette from options. On DVDs, the palette is part of the IFO file and therefore not available when reading from a dumped VOB file.	12 years ago

Michael Niedermayer	8bf16e677f	ffv1enc: allow encoding with 1 slice for CIF and smaller in version 3 the default is still 4 slices for any resolution, this just allows the user to force 1 slice.
