do you know that a 3gp file is audiovideo in android?

Assuming this is a local file, you can use MediaMetadataRetriever to get Metadata information about the media file.

Specifically, you can check if the METADATA_KEY_HAS_VIDEO is set to true.

An example in Kotlin:

        val metadataRetriever = MediaMetadataRetriever()
        metadataRetriever.setDataSource(context, Uri.fromFile(your3GPPFile))

        val hasVideoKey = metadataRetriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_HAS_VIDEO)
        if (hasVideoKey == "yes") {
          //Include in your list or do whatever work 
          //you need here

You can also use ExoPlayer and load the file, and then get a list of the tracks using


This will return an array of tracks which you can loop through and parse the format to check if they include a video track.
