Hi,

Has any thought been given to developing a Video Mixer in the same
manner as the Audio Mixer?

Something that takes multiple inputs of any format and outputs a
format useable by the current display?

This would simplify video decoders (most of which seem to implement
their own colour conversion).  A decoder can then just output their
best format which is usually the one they work in internally.
I am with you on the conversion node thing. Although the same could be achieved if we supplied highly optimized conversion routines as a public API, or at least an API that codecs can use. This may be something that BMediaTrack takes care of all on it's own. To me it seems more flexible, since you don't always have nodes involved. Actually, most of the times, you don't. Only at a later stage. 


Also, when we want to add subtitles we will need to be able to merge 2
video streams (video + subtitle)
But here I think it's better to render the text using BView drawing, since only then it will be crisp independent of the video resolution. 

Best regards,
