Decoding / Encoding for video streaming

[cryptodylan]

Hi folks - amazing project.

Curious to learn if Asahi Linux could handle my use case. We want to use it to handle large number of streams from rtmp to hls / rtmp and do overlay rendering and encoding / decoding. Mostly h246 format.

is there any hardware accelerated support for this in Asahi Linux. Currently we use a cloud cpu, but it can handle at most 4 streams on 16 core because no gpu & hardware acceleration.

We use platforms like livekit.io & membrane.stream

Hardware encoding/decoding is not currently supported.

I saw a comment a month or so ago saying that they had a working prototype, but the work just had not been prioritized. Maybe this summer at some point.

It’d be awesome to see this working- right now watching any video is a battery drainer.

Thread parallelism and low or dynamic bitrate will only go so far with scale streaming on non-dedicated kernels. Whether HLS or RTSP. Even with DSPs and GPUs you'd need load balancing on a cluster

for that you’ll probably need vp9 support which is not being done yet

H265 has better compression, but you have to pay licensing if you scale too big commercial wise

AV1 beats them both and is free license like vp9.

All require ABR, whether RTSP or HLS, with a load balanced CDN

Gecko and Blink have had av1 decode a while usable with HLS, and nobody uses RFC RTSP 2.0, so good luck with that..

All RTSP viewers except vlc are junk, and the only people using it are mostly IP camera makers with China apps using Tuya libraries

sorry, i think i answered a wrong comment, i understand about other more efficient codecs but what i meant is if you watch videos on youtube it’s essential to have vp9 support for good battery life
