Reading audio video properties from wmv and h.264 files

[vishu_gupta]

Hi All,

Apologies if my question sound stupid as i am new to this domain. I would like to know if i can use the EXif tool to read the audio and video metadata from .wmv and h.264 files. The metadata i am looking for is -
1. information about audio video track
2. presence of Audio description track
3. presence if embedded subtitile track
4. aspect ratio
5. bit rate

What all information about a media file can this tool provide?

Please let me know if the tool can do this and some guidance on how.

Thanks.
Vishal

Hi,

Yes, ExifTool can display most relevant data from video file. I don't know about wmv, but for mkv (containing h.264 as well) files, you can see (among others):
-TrackType (video, audio, subtitle...)
-TrackName,
-VideoCodec, AudioCodec, .. (MPEG4, AC3,..)
-VideoFrameRate,
-Video Width & Height,
-TrackLanguage,
-Number of audio channels,
-Audio sample rate,
etc.

To see all metadata inside video file, execute something like:
exiftool -S -g0 -All:all MyVideo.wmv

ExifTool decodes metadata from most video container formats.  Since AVCHD has very limited metadata in the container, ExifTool extracts the metadata from the H.264 video stream, but only for this container format.

Just download exiftool and drop a video file on it to see what you get.
