Alexandra Hájková	ffa190d047	Move VLC and RL_VLC_ELEM structure definitions to a separate header Use the newly created vlc.h directly instead of including get_bits when needed. The VLC and RL_VLC_ELEM structures are independent from the bitreader. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago

Reimar Döffinger	5f5e6033cd	bitstream.c: improve init_vlc error messages. Makes it far easier to spot the issue if e.g. caused by a typo in the code table. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	9 years ago
Ganesh Ajjanagadde	e11e32686f	avcodec/bitstream: replace qsort with AV_QSORT Commit `3a0a2f33a6` claims large performance advantages for AV_QSORT over libc's qsort. The reason is that I suspect that libc's qsort (at least on non LTO builds, like the typical FFmpeg config) can't inline the comparison callback: https://stackoverflow.com/questions/5290695/is-there-any-way-a-c-c-compiler-can-inline-a-c-callback-function. AV_QSORT has two things going for it: 1. The guaranteed inlining of qsort itself. This yields a negligible boost that may be ignored. 2. The more serious possibility of potentially allowing the comparison function to be inlined - this is likely responsible for the large boosts reported. There is a comment explaining that this is a place that could use some performance improvement. Thus AV_QSORT is used to achieve that. Benchmarks deemed unnecessary due to existing claims about AV_QSORT. Tested with FATE.
