Video Codecs know-how

Most Video streming is still done with h264, since this is integrated in hardware chips as encoder and decoder for many years.
HEVC or h.265 is available as hardware decoder for a few years, but encoders are always in software and therefore need a lot of power.
YouTube uses VP9 because Google bought that company and released it as opensource, but it still is extremely compute-intensive for encoding.
The NextBigThing is VVC or h.266, started in 2017 and open source released now:

The efficiency is always 50% better per generation, meaning the same looking quality costs 40mbit/s in h264, 20mbits in h265 and 10mbits in h266.

During the bleak state of MPEG licensing, free codecs are on the rise.

AV1 from AOM is 30% more efficient as h.264 and royalty and patent free.

do you know which codec is the best for 4k 360 live-streaming … ?

Der ist doch eh in der Cam verbaut? Transcoding lohnt da selten.
Ich kenne die Nokia OZO, die haben ganz brauchbare audio codecs.
Und natürlich insta360, die fand ich ganz schick.
Beide streamen direkt auf yt/fb, und können dementsprechend nur die h264 Formate die kompatibel sind.

ich habe eine Qoocam 8K , die 4 k Livestreaming können soll … , daher die Frage
