Another Green Screen

I found a bunch of videos which are giving me the green screen, where audio plays, but the video is just a block of solid green. MediaInfo shows something similar to this (some have a slightly different ‘Writing Library’) on the files in question:

I just updated to the latest release and it’s happening there, just like it was on the previous OSMC version. If you want a copy of the video file, let me know how you’d like it provided. Also, let me know if a Kodi log file would help and, if so, where you’d prefer I upload it (pastebin, etc.).

Thanks.

Does the issue occur if you disable hardware acceleration?

The bitstream is probably unsupported.

Just checked, and it does not occur with HW acceleration disabled. Gonna be annoying to remember to keep switching that on and off, but at least there’s a workaround.

Thanks.

You could just set acceleration to HD and up and it should work.

Ah, that’d work just fine. Thanks for the tip, Sam! Since these are in SD, I set mpeg2, mpeg4, and h264 acceleration to “HD and up”. That seems to be working. If I come across some HD content that gives a green screen, I’ll change them to disabled.

You shouldn’t find a lot of XVid in higher resolutions, so I think you’ll be fine.

LOL! Very good point! :sweat_smile:

However, I did find it a bit odd that I needed to turn on HW acceleration for some MPEG2 videos at just 480p because they were stuttering:
