[FFmpeg-devel] [PATCH 7/7] avfilter/vf_framerate: fix scene score with negative linesize

Also, do not overread input if linesize > width, or linesize is not divisible by 8, and use the proper rounded width/height for MAFD calculation. Signed-off-by: Marton Balint --- libavfilter/vf_framerate.c | 18 +- 1 file changed, 9 insertions(+), 9 deletions(-)

[FFmpeg-devel] [PATCH 6/7] avfilter/vf_framerate: do not calculate scene change score multiple times for the same frame

This speeds up the filter, and also fixes scene change detection score which is reduced based on the difference of the current MAFD to the preivous MAFD. Obviously if we compare two frames twice, the difference will be 0... Signed-off-by: Marton Balint ---

[FFmpeg-devel] Lagarith codec and FFmpeg

For a long time that I use the Lagarith codec. https://lags.leetcode.net/codec.html (free codec) It is one of the best lossless 24bit codec available for PC, despite being around for a long time. It does not "add" gradients on the color space when packing and the quality, well is lossless,
