I'm not available to look further in this until next week. For the time being, you might want to try to allow AVMediaTypeMuxed for audio and video devices and see if the device is then listed properly and what comes out then if recording from these. I think I don't have any devices detected to be a muxed type available, so this might need close collaboration to fix the issue. Please consider opening a ticket on trac for that. -Thilo _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
