[FFmpeg-user] Converting mp4 to mp3 has the mp3 longer than the mp4
Hello, I was trying to rip the audio from an mp4 file and then cut the mp3 file down, when I noticed something. The source video is 24m 50s in length, but when using "ffmpeg -i video.mp4 audio.mp3", the resulting audio file is 25m 28s in length, confirmed in both metadata and the Groove music player. Any idea what's going on? Thanks, Felix ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".

Thank you. What is the version of your FFmpeg? Your command work for me with the latest FFmpeg (https://git.ffmpeg.org/gitweb/ffmpeg.git/shortlog/refs/heads/master). There is a green line at the bottom of each scaled image with your command, you may try vpp_qsv instead of scale_qsv. We will fix the green line issue in scale_qsv Thanks Haihao ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe". ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe". ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org
