HEVC HW Decode

[awkimball]

System and IINA version:

• macOS 10.14
• IINA 0.0.15.1 Build 69 1.0.0 b4
• FFMPEG 4.1

Expected behavior:

Decoding and playback of HEVC encoded video, contained in MKV or MP4, tagged hev1 or hvc1.

Actual behavior:

Playback occurs at full speed but video is interspersed with blue frames every few frames, only on hardware decoding. (I can provide video recorded externally if that would help at all).

Quicktime can only play HEVC contained in MP4 using the hvc1 encoder tag, but even these have the issue.

mpv log:

Steps to reproduce:

• MPV does not have this problem.

How often does this happen?

With all HEVC encoded videos. I have played them in quicktime and MPV, neither has this issue.

@inflation Thanks, I am aware that it is a duplicate however the other issue had been marked closed. In this case is it best practice to open a new issue or reopen the old one?

@awkimball Which version are you currently at? This issue is in upstream and should have been fixed as stated in the original one.

In general, reply in the the thread if it seems to be the same issue.

@inflation The comment by @lhc70000 states that it has been fixed in 1.0.0b3 but like the issue says at the top: I am on 1.0.0b4 which is newer than 1.0.0b3 and I am certain that I am attempting to play videos encoded with ffmpeg 4.1 as well.

@awkimball Then you should remove the 0.0.15.1 version number when you fill in the template.

Because in your log file, the issue is exactly the same in the original thread. And you said you built against ffmpeg 4.1, you mean you manually build the project? Then in such case which mpv version did you use?

The current beta version 1.0.0-beta4 Build 92 only uses mpv 0.29 built against ffmpeg 4.0.1.

@inflation My mistake, I installed IINA using homebrew but when it attempted to update to 1.0.0b4 it either didn't finish, or got overwritten by the stable homebrew release. Turns out when I checked the version I opened the beta version, but in my testing used 0.0.15.1!
