Decrease CPU usage #5

Closed Vorlent closed 4 years ago

Vorlent commented 6 years ago

Kurento may be transcoding the stream and cause excessive CPU usage. This is fine if only one stream runs on a single machine but running multiple streams just isn't feasable. At the bare minimum it should be possible to run one stream per CPU core.

Possible solutions: avoid transcoding use hardware accelleration

h264 encoding is less CPU intensive but the current kurento configuration supports automatic VP8 transcoding. Removing VP8 support decreases the CPU load noticeably but it only shows a blank screen.

VP8 encoding performance with the real time option significantly decreases the CPU usage and increases quality because it avoids transcoding.
