Hi. Sorry, I think I got it wrong in my previous reply:
> I think there is no way to retrieve the information using the FFMPEG API. There is this: https://ffmpeg.org/doxygen/trunk/structAVDeviceCapabilitiesQuery.html Quoting the docs: > Following API allows user to probe device capabilities (supported codecs, pixel formats, sample formats, resolutions, channel counts, etc). Give the above API a try. > So the output in the console comes from the backend and not from ffmpeg? Well, the output comes from ffmpeg, it gets printed with the av_log() function. For the decklink '-listformats' flag, the output just gets printed and it is not stored in any structure(not even in the above API) from which it can be retrieved. That is why I had to capture the log and then parse it. > probably I have to implement this functionality directly with Dshow in Windows and v4l2 in Linux. Doing this with the decklink API for my case would be a better solution than the one I currently have. Regards.
