[Libav-user] list all available formats of webcam

[Hans, Sven]

Hi,

probably I have to implement this functionality directly with Dshow in Windows and v4l2 in Linux. So the output in the console comes from the backend and not from ffmpeg?

Mit freundlichen Grüßen / Best regards

Hi.

I faced a similar problem:

http://ffmpeg.org/pipermail/libav-user/2018-October/011413.html

I think there is no way to retrieve the information using the FFMPEG API.

As a workaround you can use a log call back to store the printed formats info and later parse that information.

Regards.

Please share if you find a better solution.
