I'm curious: Do services like Twitch specify a specific desired codec/bitrate that doesn't get transcoded? Transcoding seems like a lot of effort for lower quality end result.
If I were streaming, I would want to avoid transcoding as much as possible. Since we're talking about live broadcasting, there is a unique ability for the streamer to choose the format they upload.
- kd5bjo 7y agoIn the RTMP days, the highest quality setting in the viewer was always a straight pass through from the broadcaster, and the reduced versions were transcoded in the data center to fit down lower-bandwidth last-mike pipes.
- thomastjeffery 7y agoGotcha. For whatever reason, I had forgotten about lower-bandwidth copies.
- slimscsi 7y agoSame in the HLS days. What used to be called “source” was just a remux from rtmp to ts.
