Hi There, I’m looking into using FFMPEG for its DeckLink device control. The capture part of the API seems fairly fully featured, however the output/playback controls seems to have some strange limitations. Specifically, on output, there is a hard-coded limit of only 8 channels of audio. What’s strange, is that the capture partition can handle up to 16, which makes sense considering most DeckLink cards have SDI input/output, and 16 channels is a standard workflow for SDI. Also, is there a reason why only 2 and 8 channels are supported, instead of just “n” channels (4 or 6 channels, for example)?
Would it be possible to output 16 channels of audio? Is there a better way to do this (via the command line?)? Could a custom version of the decklink_enc files be built to handle 16 channels or is there some other limitation I’m not aware of? Thanks in advance, I really appreciate any advice/ideas here. Also, is there a specific reason that input/output are limited to only 48khz for audio? I’m guessing this is specific to DeckLink cards, but I haven’t found a specific reason yet. ~Thomas Matthias _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
