NEON optimization? about alvr

[JackD83]

The client is currently using android.media.MediaCodec to decode the video.
NEON and dav1d could be a great improvement, but I probably lack the skills to do it myself :(

After reading a little about this topic, I'm pretty sure the decoder is already using this kind of optimization. There are some papers describing this in 2013 here

After seeing the results back then (720p (1280x720) streams at 30 frames per second) I think this is used to decode our 3k stream at 72fps

The new part with dav1d is that its used for AV1

I have some error regarding gradle in android studio.
Could you edit the build.gradle like this and test it:

externalNativeBuild {
cmake {
arguments "-DANDROID_ARM_NEON=ON"
cppFlags ""
}
}

[Sztrovacsek81]

I think I was misleaded by this AV1 experiment (there is no hardware AV1 decoder yet).

I think that the flag -DANDROID_ARM_NEON=ON has only influence on our own code that does not profit from the optimization
