[Libav-user] DeckLink libavdevice

Taking Nicolas George's suggestion, I have created a basic libavdevice
for Blackmagic's DeckLink HD-SDI cards. I'm thrilled to have it working
to any degree (much easier than I expected), but still have several
issues to work out. Where is the proper place to ask questions for a new
libavdevice? ffmpeg-dev or here or ?
The most important is that the normal use of the device will be to
output a specific frame size/fps and the audio is _always_ 48k s16le 2,
8 or 16 channels.
The issues I'm not sure about are:
1) Automatically converting audio to 48k, s16le, 2/4/8 channels.
2) Automatically scale/crop video to output.
3) Proper configure detection of installed DeckLink includes.
And of course getting past the patch review ;-) I am certainly not
compliant at this moment!
If creating an input device is as easy as this has been so far, then I
hope to create a capture device next.
