[FFmpeg-devel] [PATCH] vf_fps: when reading EOF, using current_pts to duplicate the last frame if needed.

Fix ticket #2674 Tested with examples from ticket 2674. --- Update the Patch with the correct number of duplicate showing. For exmaple, in case we up-sample one second video at 24fps by 2, we should be getting 24 duplicate frames. ffmpeg -loglevel verbose -i 24fps.avi -vf fps=48 -f null -

Re: [FFmpeg-devel] [PATCH] vf_fps: when reading EOF, using current_pts to duplicate the last frame if needed.

See new patch. Getting 12 frame out when down-sample (instead of 13) === I tried it against ticket 2674 and here is the output: ffmpeg -loglevel verbose -i 24fps.avi -vf fps=12 -y 12fps.avi ffmpeg version N-87234-g9a32769f5e Copyright (c) 2000-2017 the FFmpeg

Please find attached new patch. I tried it against ticket 2674 and it seems to work Here are the output: For the up-sample, getting 48 frames out, instead of 47 -- ./ffmpeg -loglevel verbose -i 24fps.avi -vf fps=48 -y 48fps.avi ffmpeg version N-87234-g9a32769f5e

[FFmpeg-devel] [PATCHv12] libavcodec: v4l2: add support for v4l2 mem2mem codecs

This patchset enhances Alexis Ballier's original patch and validates it using Qualcomm's Venus hardware (driver recently landed upstream [1]). This has been tested on Qualcomm's DragonBoard 410c and 820c Configure/make scripts have been validated on Ubuntu 10.04 and 16.04.

[FFmpeg-devel] V4L2 M2M v12

Improvements on v12: - fixes error detection during context configuration. - closes the driver properly on exit. - removes lazy_init field from V4L2Context. - add more clarity to the context initialization API. Patch applies on top of: 86eb505 Changelog: add vp9 tile threading support
