Available key values #202

Looking at the docs - http://wseemann.github.io/FFmpegMediaMetadataRetriever/apidocs/index.html

I can't find what key values are available when calling, for example:

mmr.getMetadata().getLong("????");

Is there any documentation on this?

I'm trying to find a videos timescale. When I run a command I can see it the timescale - 14848 tbn

You can use mmr.getMetadata().getAll() which returns a HashMap containing the available key/value pairs.

See: http://wseemann.github.io/FFmpegMediaMetadataRetriever/apidocs/wseemann/media/Metadata.html#getAll()

@wseemann Thank you for the quick reply.

mmr.getMetadata().getAll() returned the following:

{video_codec=h264, rotate=0, video_height=720, framerate=29, major_brand=isom, video_width=1280, audio_codec=aac, filesize=24727966, encoder=Lavf58.12.100, minor_version=512, duration=11000, chapter_count=0, compatible_brands=isomiso2avc1mp41}

The timescale is not here?

getMetadata() provides all of the available metadata for the file. timescale isn't a supported FFmpeg metadata field. https://wiki.multimedia.cx/index.php/FFmpeg_Metadata
