Is it possible to have the transcoder generate an "overlay only" video track on an audio stream?
We'd like to stream some audio only channels (with fixed names) and, in case, inject a static image stating that "This stream has no video!"
I tried in this way:
* I've set up the "overlay" section in the "decode" block (to have this overlay applied to all the encoded streams)
* I created a new "Encode" block with H.264 encoded video (width and height equal to the overlay one), AAC encoded audio, with no overlay (since it has already been defined before)
The result is an audio-only encoded file coming from the transcoder.
Thank you in advance,
