Yes, RTSP contain MPEG2TS. I forgot about it. sotaro ----- Original Message ----- From: "Andreas Gal" <[email protected]> To: "Sotaro Ikeda" <[email protected]> Cc: [email protected] Sent: Thursday, August 1, 2013 9:52:10 PM Subject: Re: [b2g] Youtube Live Support on B2G
Yeah, DASH is a dead end. We should not enable that. Doesn't RTSP contain usually MPEG2TS streams? Thinker just said we will enable that. Support for HLS would be trivial if we have MPEG2TS support. The question is though whether we really need it. Maybe MSE will be ready soon and it seems YT will support it?
