FFmpeg AVI to MP4 preserves sound, but not images [migrated]
21 février 2013, par user1711384Working with FFmpeg at a conversion (any file to MP4 (H.264/AAC)) :
ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 1 -an -f mp4 -movflags faststart /dev/null
ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 2 -c:a libfdk_aac -b:a 128k -movflags faststart xxx.mp4 2>&1With MPEG and WMV file it's working. With two different AVIs it didn't work. Logfiles from path 1 aren't generated and output 1 is empty, output 2 of course generates an error.
After removing
-profile:v baselinein both commands, the video file is successfully generated, but it's not possible to play it in JW Player (sound yes, but no image).This is the result of the first command :
