Hi, When I run the command
./ffmpeg -debug 1 -f pulse -ar 44100 -ac 2 -channel_layout stereo -thread_queue_size 1024 -i alsa_input.pci-0000_00_14.2.analog-stereo -f v4l2 -use_wallclock_as_timestamps 1 -itsoffset 1.70 -channel 1 -video_size 720x576 -pix_fmt yuyv422 -thread_queue_size 1024 -i /dev/video0 -c:a pcm_s16le -channel_layout stereo -c:v ffv1 -level 3 -g 1 -aspect 4:3 -pix_fmt yuv422p -top 0 -vsync passthrough /Store3/Test/t_`date +%Y%m%d_%H%M`.mkv I have a perfect output without any error but I don't have preview. When I add -aspect 4:3 -f sdl "Dazzle output" at any position I get the well known RED error message Application provided invalid, non monotonically increasing dts to muxer in stream 0: I know it's very difficult to get ride of this error, so there could be a workaround: pipe the output file to ffplay. Unfortunately I can't find the syntax when the output is a file but only when this is a raw video stream. Could you help me for that?
