Find if video file has audio present in it [duplicate]

Answer 1

Found a round about to solve this problem. This seems to answer the question I asked.

ffprobe -i input.mp4 -show_streams 2>&1 | grep 'Stream #0:1'

Answer 2

If you only want to know if there is audio and don't care about the stream details you can run the following command, which will extract the duration of the audio stream in the input file. If the response is null/whitespace the input file has no audio in it.

Command:

ffprobe -v error -of flat=s_ -select_streams 1 -show_entries stream=duration -of default=noprint_wrappers=1:nokey=1

Answer 3

If it is normal video file from the local path, you can do something like this to find whether video has audio file or not.

You need to look into the MediaMetadataRetriever

By using METADATA_KEY_HAS_AUDIO you can check whether the video has the audio or not.

private boolean isVideoHaveAudioTrack(String path) {
        boolean audioTrack =false;

        MediaMetadataRetriever retriever = new MediaMetadataRetriever();
        retriever.setDataSource(path);
        String hasAudioStr = retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_HAS_AUDIO);
        if(hasAudioStr.equals("yes")){ 
         audioTrack=true; } 
        else{ 
        audioTrack=false; }

        return audioTrack;
    }

Here path is your video file path.

PS: Since it is old question , i am writing this answer to help some other folks , to whom it may help.

ffprobe -v fatal                         # set log level to fatal
        -of default=nw=1:nk=1            # use default format and hide wrappers and keys
        -show_streams                    # show info about media streams
        -select_streams a                # show only audio streams
        -show_entries stream=codec_type  # show only stream.codec_type entries
        video.mp4                        # input file

A media file contains an audio stream returns:

audio
1
0
0
0
0
0
0
0
0
0
0
0
und
SoundHandler

A media file contains no audio stream retuns empty result.

A non-media file also returns empty result. If you want to return an error message for non-media files and on any other error case, use -v error instead:

ffprobe -v error                         # set log level to error
        -of default=nw=1:nk=1            # use default format and hide wrappers and keys
        -show_streams                    # show info about media streams
        -select_streams a                # show only audio streams
        -show_entries stream=codec_type  # show only stream.codec_type entries
        video.mp4                        # input file

So, you take this instead of empty result:

non-media-file.zip: Invalid data found when processing input

Answer 5

I would use FFprobe (it comes along with FFMPEG):

ffprobe -i INPUT -show_streams -select_streams a -loglevel error

In case there's no audio it ouputs nothing. If there is an audio stream then you get something like:

[STREAM]

index=0

codec_name=mp3

codec_long_name=MP3 (MPEG audio layer 3)

profile=unknown

codec_type=audio

codec_time_base=1/44100

etc

etc...

[/STREAM]

That should be easy enough to parse regardless of the language you're using to make this process automated.
