GFX Video: "hardware decoding + overlay" (MATE)

[star-buck]

Issues:

• video output shows visible frizzles (aka thin horizontal lines) for all faster moving "sharp borders"
• video cannot be overlayed with menu popus, etc.
• a simple song mp3 doesnt show standstill video img (will show what i mean in the video comparison)
• firefox: youtube does not play videos smoothly, 480dpi already stutters, 720dpi unwatchable

Will look into it. If you have any sample videos that highlight it best that would help.

literally not possible to fix with overlays. It sucks. Same for Mate image too

a simple song mp3 doesnt show standstill video img (will show what i mean in the video comparison)

Should be quite easily fixable. We can make the mpv config clever and say "use vdpau for these codecs, not others".

firefox: youtube does not play videos smoothly, 720dpi almost unwatchable (i assume it is using opengl and not vdpau?)

It's at least using GL for rendering. It could still be using vdpau for decoding, I'll find out.

Frazzles fixed! I wasn't double buffering my output. That video you sent me helped, that intro is super smooth now

I'll get that packaged along with the "a simple song mp3 doesnt show standstill video img" fix.

Video looks good.

But did you notice the desktop looks kinda shaky? Is it because of the shadow fix or the libvdpau-sunxi update (i applied the deb immediately without trying the img with frizzles first)?

I also noticed the Compositor is now set to "Instant apply", but if you set it to step 2, one can see the glitchiness. Same goes for maximizing then grabbing the window from the border to drag it around. I could make a mobile video, but it should be easily spottable?

Will investigate more tomorrow, i hope it's just an unnoticed sideeffect and therefore fixable.
