When I try to play a bunch of webm files (per videos-archives-select a directory-Play) sequentally, some files don´t play (a screen of rubbish rainbow lines appears) and I have to reboot.
Any ideas? Bad video codec?
The directory plays well on Kodi pc brand and also on Kodi Ipad installation
Well to judge that you should tell us which codec they are.
It would be good if we could find out more about the file you are having issues playing. Please see the ‘Playback related issues: using MediaInfo’ section in this Wiki resource for further help How to submit a useful support request - General - OSMC
And logs in general help us to help you.
Webms typically use vp8 video. This codec cannot be decoded in hardware on a raspberry pi.
When the pi has to decode the stream in software, it will be pushed very hard if the resolution is too high.
I am seeing this issue as well. When playing the webm video the screen displays static multicolored lines covering the whole screen, and it is not possible to get the UI back.
SSH works without problem, and there is no CPU load. The only way to get the UI to work again is to reboot.
The problem is 100% reproducible with e.g.:
http://cdn.media.ccc.de/congress/2016/webm-hd/33c3-8167-eng-deu-Everything_you_always_wanted_to_know_about_Certificate_Transparency_webm-hd.webm
The video is valid when playing it on an Ubuntu desktop.
Movie name : Everything you always wanted to know about Certificate Transparency
Writing application : Lavf56.40.101
Writing library : Lavf56.40.101
Video
ID : 1
Format : VP8
Codec ID : V_VP8
I understand that this codec cannot be decoded on the GPU.
I would expect the playback to be choppy with many dropped frames when decoding on the CPU, but I do not expect the UI to stop functioning all together and only show screen artifacts reminiscent of the c64 loading screen.
To me it looks looks like the graphics stack crashes somewhere. I do not see anything interesting in dmesg relating to playback of the video.
Some other notes:
- I seem to be wrong about it being 100% reproducible, the link i gave sometimes works. I have more luck reproducing the problem with this link:
http://cdn.media.ccc.de/congress/2016/webm-hd/33c3-8315-eng-deu-A_world_without_blockchain_webm-hd.webm - Audio playback continues without a hitch
- The CPU is not under load (16%)
Kodi log looks sane…:
