I'm sorry if this question is not suited for stackoverflow but I'm trying to understand how does videostream for chromecast works. Technically speaking chromecast is not able to reproduce .avi files but still, they play if you use the solution mentioned before.
My question is, are videos selected being live transcoded into h264?
avi is a container format. It is possible (in fact very common) to put h.264 video inside an avi file. If the file is not h.264 (or vpX) it must be transcoded
