LibDRM(bpo) Video looks not Ok

[bester69]

hi,

Ive upgrated to backports libdrm's and now videos looks like with less brightness or less quality in the codec copression.. I dont know what exactly is, thought its very tinny the difference i can see it, and gets the feeling something is not ok.



Any idea

I don't know what it is either. Maybe some error messages in your logs , or something that shows there really is something wrong ?

I think It has to be with ffmpeg version Ive installed and this libdrm version, Im going to install another ffmpeg version.. right now Ive installed 3.4.2-2~obs (from steve's repos), gonna try updating ffmpeg or rollingback to stable.. I will tell you if it fixed.

Ok, It was the codecs i was using.. Ive installed deb-multimedia (stretch-backports brach) (3.4.4), and It has installed more new packages I didnt have installed, so now It looks Ok with libdrm's bpo.

Thanks.

I've found that ffmpeg, especially if you want to get va-api hardware decoding working, is sensitive to the Mesa and libva libraries it's built against. Mesa uses libdrm and libva as build-depends, so it's best to use versions from one repo instead of mixing them up like that.

ok, that makes sense, I will consider it.


Thanks Steve
