Cannot select a higher h264 profile #262

Open ryango opened 11 months ago

Any plans to resolve [ISDK-1590]?

We have been using 1080p30 for a while with no trouble but on recent iOS versions (16.4+) notice this issue much more frequently. The encoder dies and the only way to detect it is to check the stats and see local send framerate goes to 0. Republishing the track can fix it but will fail again in under a minute.

Twilio video is in need of a higher resolution hardware accelerated codec which could be solved by allowing for a higher level profile. VP8 and VP9 being software encoded is prohibitively expensive, results in hot phones and throttling when sending more than one stream even on the latest hardware.

I'm happy to take the compatibility hit, we target higher end devices and would much prefer higher resolution.

It appears the h264 encoder dying happens when 1080p+ and the content is relatively static.
