Guillaume Martres	f90281ca97	hevc: Correctly set time_base - Try reading the time_base information from the VPS too, not just the VUI - Only set time_base when an SPS is activated, not when it's decoded. - Reduce the fraction before setting it. - Don't set anything if the fraction is invalid (because the VUI is not present or because the encoded value is invalid).

Michael Niedermayer	f1783c05f1	Revert "avcodec/hevc: calculate checksum only if AV_EF_EXPLODE is set" This reverts commit `758b6d39f6`. Requested-by: smarter "now that http://git.videolan.org/?p=ffmpeg.git;a=commit;h=97de206b44a48da726807cc3e7b9448a8112760b has been merged, http://git.videolan.org/?p=ffmpeg.git;a=commit;h=758b6d39f685a510f48ff9e4c05fffa859d23c42 could be reverted, this would reduce the delta with libav (and it makes sense)"	11 years ago
