Andreas Rheinhardt	790f793844	avutil/common: Don't auto-include mem.h There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	11 months ago
杨亚磊 via ffmpeg-devel	ee8d2ece7b	lavfi/framequeue: remove redundant logic code In this logical branch, fq->queued and fq->allocated must be equal. Deleting this code will make it easier to understand the logic (copy the data before tail to the newly requested space) Signed-off-by: yangyalei <yangyalei@xiaomi.com>	1 year ago

Muhammad Faiz	fc3a03fcf9	avfilter: take_samples: do not directly return frame when samples are skipped Modifying data pointer when skipping samples may make it unaligned. Workaround for Ticket6349. This should fix the crash of ticket's testcase and a crash/regression with avxsynth (reported by Michael Niedermayer). Also change frame->nb_samples < max to frame->nb_samples <= max. This improves performance.

Nicolas George	383057f8e7	lavfi: make ff_framequeue_skip_samples() more useful. Instead of just updating statistics and leaving the work to the call site, have it actually do the work. Also: skip the samples by updating the frame data pointers instead of moving the samples. More efficient and avoid writing into shared frames. Found-By: Muhammad Faiz <mfcc64@gmail.com>	8 years ago
