Hi,

I have a TV connected with HDMI to my PC and it runs fine more or less. However while playing full hd video it is far from smooth and I would like to do something about this :)

Hardware is
MB ASUS P8Z77-V
CPU Intel Core i7 3770
8GB RAM
using integrated video

I guess external videocard will help, but still. Do you think that I need one? If so - any recommendations? I don't need 3d performance, just good acceleration for HD video.

Thanks

stoil,

That system should be able to do HD video with the framebuffer driver - it should not need any help.

Please post your
Code:
emerge --info

Also the output of
Code:
groups
for your normal user. Its possbible to have accelerated graphics set set, then not use them.

What does glxinfo say about hardware acceleration ... its in the first few lines of output.

when I say that it is not smooth - it is visible when for example the picture is moved relatively fast right/left. In such case areas of the picture are not refreshed fast enough.

stoil,

Your emerge -- info is good.
What of the other two questions I asked?

Please post /var/log/Xorg.0.log onto a pastebin, so we can see how X is running.
What video player application are you using?
What USE flags is it built with?

Horizontal video artefacts sound like an interlace problem but you should not be using interlace on HD.
You can ... but you shouldn't, unless your source material is produced using interlace.
Then you need to use a deinterlace filter on playback.

While I was collecting info suddenly the problem went away. The difference was that monitor was duplicated to the TV.
When I made it separate it still worked fine. I checked refresh rate and it was at 30Hz. Once I changed it to 50 - the problem was reproduced.

Since the video itself is with lower rate this should be the reason, right?

I guess this has nothing todo with applications, but still - here are the use flags. I can provide X logs if still needed.

sh-4.3$ equery uses mpv
[ Legend : U - final flag setting for installation]
[ : I - package is installed with flag ]
[ Colors : set, unset ]
* Found these USE flags for media-video/mpv-0.9.2-r1:
U I

- - doc-pdf : Build documentation in pdf format
+ + drm : Enable Kernel Mode Setting / Direct Rendering Manager based

+ + dvb : Add support for DVB (Digital Video Broadcasting)
+ + dvd : Add support for DVDs
- - egl : Enable EGL backend for X11 OpenGL video output

+ + enca : Enable support for charset discovery and conversion using

app-i18n/libguess
- - libmpv : Build mpv shared library
+ + lua : Enable Lua scripting, OSC (On Screen Controller) GUI and

hm. it is not refresh rate. It works fine only if monitor and TV are displaying the same thing. I'm not sure what could be the reason.

Isn't HD material made for 60Hz ?

You want 60HZ for HD video and if you have enough ram to hold the video file, copy it to /tmp then play from there to avoid I/O on drive.
