检测MOV文件中丢失的音频

Question

i'm curious if there is a way to detect if audio is missing or broken from a MOV video file. Recently there was a MOV file which was playable, but the audio was "missing".

I tried ffmpeg to get specific errors but it did not give me any. I only noticed that the audio bitrate was very low, 2kb/s. Apart from checking the audio bitrate is there a way to detect such broken video clips with ffmpeg?

The mising audio could have been caused by an unsuccessful copying of the file.

Answer 1

ffmpeg -i movie.avi -af volumedetect -f null -

这将打印出一个直方图，告诉您文件中的音量
