I'm not familiar with that. If you can post a small, self-contained example of what you are currently trying, possibly someone else can answer.

Yes, I'm trying to open a webcam as an input device (I take frames out of it). I know how to open it and capture frames, but it is opened in rawvideo mode and I need it to be MJPEG which I know is supported by the webcam. I guess the option is passed to the API function avformat_open_input(), which receives an AVDictionary **, but I don't know what options are available neither which values can be passed. Any help or hint you can give me is a lot. Thank you. Hamilton. On 7/2/20 7:54 PM, Brad Hards wrote: > I think the answer often depends on what the dictionary is being used for.
