[Mlt-devel] Adding a producer

2013-04-19 Thread Thomas Vecchione
I am just evaluating at this point, and am far from a professional coder. I wrote a basic python program to take output from ATEM devices from Blackmagic Design and record the output and restream via ffmpeg. Then I discovered this lib, which seems like exactly what I want to do with the exception

Yeah, quite simply, MLT is not well suited towards your needs. It converts all inputs to uncompressed (if not already). It does not support the notions of "-vcodec copy" or lossless editing of compressed inputs ("edit without re-encoding by splicing on a keyframe"). It is overkill for something lik
