* enable ffmpeg native h26x software decoders for all platforms
* h26x software decoders depend on hwcodec feature, so all platforms
enable it, software h26x decoders are always available like vpx, no available check and no option
* ffmpeg:
- build: mac arm64 build ffmpeg with my m1, others build with ci
- version: win/linux use ffmpeg release/5.1, becaues higher version require higher nvidia driver, other platforms use release/7.0
* test:
- ios not test.
- android: sometimes the screen will appear blurry, but it will recover after a while.
- arm64 linux: test a example of hwcodec repo
