I didn't notice the answer above, I thought my answer will got in the September folder with the same name.
So to answer Claudiu, the simplest CL: ./ffmpeg -debug 1 -f v4l2 -i /dev/video0 -c:v ffv1 /Store3/Test/t_`date +%Y%m%d_%H%M`.mkv -f sdl "Dazzle output" give the same issue/pattern/drops and the CL without sdl ./ffmpeg -debug 1 -f v4l2 -i /dev/video0 -c:v ffv1 /Store3/Test/t_`date +%Y%m%d_%H%M`.mkv output the yellow messages, not the red message "Application provided invalid, non monotonically increasing dts to muxer in stream 0: xxx >= xxx", BUT still has drops. CPU AMD FX8120 3.1MHz, about 25, 30% usage, nothing noticeable. I don't have another capture device. I hope to get an answer, I am stuck in my project. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
