How to get codec info using Python binding?

Postby peppy.player » 12 Feb 2023 23:17

Hi,

Using the Python binding I need to get the codec info about HTTP stream. In the VLC UI it looks like this:

Using this Python code:

Code: Select all

track_info = self.media.get_tracks_info()
I can get the following information which includes: channels, codec (fourcc string) and rate:

Image

Where can I get such info as 'Bits per sample' and 'Bitrate'?

Thank you!

Thank you! I was able to get the bitrate using the referenced MediaStats object:

Code: Select all

media_stats = MediaStats() if self.media.get_stats(media_stats): bitrate = round(media_stats.demux_bitrate * 8000)

The only missing parameter is 'Bits per sample'. The MediaStats doesn't have it. Any idea where that could be?

Thank you!

Bits per sample are useless. It's almost always 32 since VLC almost always decodes to single precision.

And if you were hoping it meant something else, well, it doesn't.

OK, but it's not hard-coded, right? I hope there should be some object in the Python bindings from which it could be fetched.
Thank you!
