Can you guys currently play HEVC (H.265) videos?

General system Gaming, sound and video

Just asking 'cause I suddenly can’t. Was working about 2-3 month ago. Lately I only worked with x264 and VP9 (which both still work) but yesterday I did a x265 encode and when I tried to play the video it was stuttering, like playing with 1/3 speed.
I use VLC, so I checked the settings, but everything looks fine and HW acceleration is enabled. CPU usage is just at ~6% when trying to play the video.
libva-intel driver is installed and libde-265 is also installed.
I also tried Dragon Player with the same result.

CPU is i5-10210U

Any ideas?

I’ve checked only mpv so far, it works for me (Nvidia proprietary drivers, LTS Kenrel, KDE)

Probably it’s some intel driver problem?

Working here too using smplayer. I don’t have NVIDIA but using latest kernel and kde

If using intel drivers, have you tried using modesetting? It is recommend for most intel iGPUs.

Not yet, will try at evening.
I wonder why both, VLC and Dragonplayer don’t just use CPU decoding when HW decoding doesn’t work. Couldn’t find a setting to disable HW in VLC, Dragon Player doesn’t seem to have any settings at all :grin:

*edit" Never used mode setting before, so I just quickly checked the net and it seems it’s connected to X. I’m on Wayland, does this still apply? And wouldn’t that effect all codecs? As I said, x264 and VP9 run fine, even with really high bitrate (50Mb/s+).

OK, time for an update. This is a really strange bug.

First I have to admit that it was dumb that I didn’t immediately try other HEVC videos. But hey, it was late yesterday and I was pretty wasted :woozy_face:

Anyway, when I got home from work today, I tried to play other HEVC videos. And they all played fine!

So I encoded some other video with the same settings I used yesterday…and again it didn’t work correctly in both players.

My next guess was that maybe Opus-audio in the MP4 container is the problem. So I did an encode with a matroska container instead, but still the same.

So I thought maybe it’s the combo of HEVC/Opus. I did AAC instead of Opus in a matroska container and suddenly it worked! BUT: AAC in a MP4 container again gave me the faulty playback :crazy_face:

I’m completely out of ideas now.

Here’s how it looks (and sounds :hushed:) like when I try to play the video on VLC and Dragon Player:

Here’s how it should look and sound:

And here’s the file if anybody wants to check:

BTW: It plays absolutely fine on my phone :slightly_smiling_face:

Strange! Thx for checking!

Shall I try mpv? I always hated it when I had it installed some time ago. No explicit reasons, I just didn’t like it.

I like it’s minimalism :smiley:

Plays fine here with AMD RX 590 on KDE Wayland. :wink:

Edit: It’s playing using Celluloid.

Edit2: It works okay also with MPV but on VLC it’s like your example …no good!

Lol, just installed mpv and it works! That makes you the mvp @xircon :wink:

Yet still a strange, but somehow interesting and fascinating bug!

edit I marked the post from @xircon as solution. I’m not expecting anybody to go deeper on this. Except anyone really wants to, of course :smile:

Thank you for checking this out and confirming the bug for VLC!

Can I recommend:

1 aur/mpv-uosc 4.7.0-1 [+2 ~1.26]
    Feature-rich minimalist proximity-based UI for MPV player.
2 aur/mpv-uosc-git 4.5.0.r4.ge33db65-1 [+4 ~0.08] [Installed: 4.7.0.r39.g442fe6b-1]
    Feature-rich minimalist proximity-based UI for MPV player

For a more attractive interface.

Every now and then i try vlc again to see if it has finally become usable again and every time i go back to mpv because something is still broken in vlc. the last time i tried it 2 weeks ago it crashed every time i tried to activate image adjustment. I leave in the future the fingers of this shit. mpv runs and runs and runs …

If you’re looking for an interface a la Media Player Classic, see Mpc-qt, it’s in the AUR :
