syncplay-android can't play hevc 10-bit video

[soredake]

Tested with jellyfish-3-mbps-hd-hevc-10bit.mkv from https://www.larmoire.info/jellyfish/

The app supports as many formats as the device internally supports especially when it comes to highly compressed formats like HEVC with high bit depth such as 10bit or 12bit. My main phone plays the video without issues but it doesn't work on one of my old phones

This will be automatically solved if at some point i make the app wrap ffmpeg just like VLC does. Road map might go as mentioned here #42

@soredake yeah, you're right, my device can't hardware decode hevc 10-bit, same video in vlc produces garbled output and lags very much, mx player plays it correctly, lags as well but slightly less.

[yuroyami]

Fixed in version (0.12.0) with the introduction of mpv.

@yuroyami i tried playing jellyfish sample and got only black screen with mpv, with anime encoded in 10bit i got same black screen and crash after seeking.

@soredake Seems like mpv is not falling back to software decoding when the hardware codec is missing, thanks for testing

[yuroyami]

@soredake I've added some mpv-related settings inside the room in v0.13.0, where you can enable/disable hardware acceleration, and also use "gpu-next" rendering backend, I dont even know what it is but mpv claims it's a new improved rendering engine or something, it may help

Also, it seems like mpv libs weren't falling back to software acceleration (as mentioned in this mpv-android release)

Let me know if that helps with this case

Yeah, hevc 10 bit are still not working.

@soredake This seems more like a device issue to me. What's the test result on mpv-android

[soredake]

Correction, no videos are working without gpu-next option: #85
And with gpu-next, hevc 10-bit are finally working, although with unwatchable frame rate, vlc/mx player give me much better frame rate with software decoding, but that's a mpv-android/libmpv/ffmpeg problem, will report to them.

@soredake reported to upstream mpv-android/mpv-android#855
