However, I started to notice an issue with the HW+ decoder on H264: a lot of times, somewhere at the start of the video, the image freezes. Meanwhile, audio and subtitle tracks continue. This is easily resolved by just skipping a few seconds forwards or backwards, but it happens so often that it is a bit annoying. So I'm wondering if this is a known issue and if it has a known solution, despite that I can't seem to find anything about it after searching the forums.
I haven't bothered with providing custom codecs as I figure that isn't needed unless MX Player asks you to, but I did notice that MX Player uses the Neon codecs on my Android TV.
Things I've tried so far:
- Use the alternate HW+ decoder. Unfortunately this seems to perform not as good on high bitrate videos, and wide color gamut support seems absent on HDR videos, so I figured this one has more downsides than the original one.
- Disable H264 support on the HW+ decoder, so that it uses the HW decoder by default for H264. This works quite well, but for some reason, HW decoder seems to fail on many of my videos, causing MX player to fall back to SW, which gives noticeably worse performance and picture quality on my Android TV.
If I can't solve the freezing image on the HW+ decoder, I'd be interested to know how to best debug failures of the HW decoder so I can more reliably fall back to HW for H264.
