Some HEVC MKV files have frozen video
Freezes happen either at first frame or within the first 10 seconds. Audio continues to play. QA indicates this might not be taking HW decode path. Example files:
- http://demo-uhd3d.com/fiche.php?cat=uhd&id=21
- http://trailers.divx.com/hevc/TearsOfSteel_4K_24fps_9500kbps_2aud_9subs.mkv.

So, it tries to open the NDK, then fallbacks to avcodec, and sw decode -> slow.

@Dekans I see in our tracker, QA tested a few days ago with the 3.0.0 release, and repro'd the issue still. Are you sure fix made it into the release?
- Maintainer
No, we don't.
TearsOfSteel_4K_24fps_9500kbps_2aud_9subs.mkv has an incorrect profile regarding its 10 bits encoding.
But we have a lead on how to get it right.

Looks like the Hispasat file also still failing, fyi.
- Maintainer
It should be better with v3.0.2 & 3.0.3 (coming in a few hours)
@Dekans So, I have a 3.0.3 nightly from today that can't play it (and has real problems with some other test files), but looks like my play store app (where I think I'm in the beta list) has updated to 3.0.3 and Hispasat file plays beatifully, and the other problem file plays smooth/fine.
So, is 3.0.3 in beta, or public release now?
- Maintainer
3.0.3 is still beta, stable release next week.
@Dekans just checking in on ETA of 3.0.3 release. Did I miss it?
- Maintainer
@davebytes it has been released this week. (As v3.0.4)
okay, looks good to me, passed along to QA to verify.
@Dekans apologies, QA verified, feel free to close.
