flv
video tomp4
usinga264
, but the result video has a out of sync audio/video. The audio seems ok but the video seems slow and therefore out of sync with the audio.Here is the command I am running :
/opt/local/bin/ffmpeg -i complaint.flv -f mp4 -vcodec libx264 -acodec aac -copyts -strict experimental -fpre /opt/local/share/ffmpeg/libx264-lossless_slow.ffpreset -ab 44k -threads 0 -crf 23 complaint.mp4
And the output :
Desktop /opt/local/bin/ffmpeg -i complaint.flv -f mp4 -vcodec libx264 -acodec aac -copyts -strict experimental -fpre /opt/local/share/ffmpeg/libx264-lossless_slow.ffpreset -ab 44k -threads 0 -crf 23 complaint.mp4

[aac @ 0x7fb361804a00] Qavg: 4519.618as additional test I did :
ffmpeg -i out.mp4 -i scaledSquare.png -filter_complex " [0:v][1] overlay=100:100:enable=’gte(t,0)’" -y test3.mp4
which supposed to add the shape from all times greater than 0, which works fine , shape is getting added for the whole duration of output.
So I am not sure why the enable option does not work when I specify something like enable=’gte(t,3)’ or enable=’between(t,1,3)’ here.
and just for additional information :
I created the original mp4 file (out.mp4) by adding an mp3 file to one png image as belowffmpeg -i images/08.png -i audio_123e4567-e89b-12d3-a456-426655440000.mp3 -pix_fmt yuv420p out.mp4
