Andreas Rheinhardt	9faf3f8bb0	avcodec/parser: Don't return pointer to stack buffer When flushing, the parser receives a dummy buffer with padding that lives on the stack of av_parser_parse2(). Certain parsers (e.g. Dolby E) only analyze the input, but don't repack it. When flushing, such parsers return a pointer to the stack buffer and a size of 0. And this is also what av_parser_parse2() returns. Fix this by always resetting poutbuf in case poutbuf_size is zero.

James Almer	3735d55af3	avcodec/parser: move parsers list and related API to its own file And add it to the CONFIGURABLE_COMPONENTS list in Makefile. This way, changes to the new file will be tracked and the usual warning to suggest re-running configure will be shown.

wm4	948f3c19a8	lavc: Make AVPacket.duration int64, and deprecate convergence_duration Note that convergence_duration had another meaning, one which was in practice never used. The only real use for it was a 64 bit replacement for the duration field. It's better just to make duration 64 bits, and to get rid of it.

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
