RE: vaapi-sse4: Deinterlacing Testing - alex.ba - 2014-05-04
Hi all,
I have a few questions on Ubuntu. Maybe someone has an idea.
1) Is it possible to disable that purple Ubuntu Screen at statup? I would prefer just a black screen until XBMC has started. Same for the shutdown?
2) Sometime the HDMI Port is disabled (if I switch on the TV too late). Is there an option to force the HDMI Output.
3) Would it be possible to force an specific resolution? Best would be that HDMI is always enabled with 1920*1080.
4) Are all fixes from Gotham stable included in your release?
Thanks a lot for your great work. I really like your PPA :-)
Best Regards,
Alex
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-05-04
1) yes
2) no
3) Can be done via drm_kms_helper but you will loose audio
4) yes
RE: vaapi-sse4: Deinterlacing Testing - CrazyCoder - 2014-05-05
BTW, tried the splash screen via plymouth, doesn't work for me, probably because of https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/1309617 .
This guide should probably also mention that one has to add "splash" to the kernel options in grub config.
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-05-05
Added, thx.

Thanks a lot for the information and update for the splash :-)
Regarding to the HDMI Output. A working solution is to put a EDID Manager between TV and PC. It works for me on my main system. I just wanted to know if I could save the money for a second device and solve the problem via software. But if it's not possible then I will buy a second EDID manager.
Best Regards,
Alex
RE: vaapi-sse4: Deinterlacing Testing - fritsch - 2014-05-05
I wrote a howto in the amd oss vdpau forum on howto dump the EDID and overwrite it with drm_kms_helper and force the output to enable. Sadly I lost my Audio with that hack. So I don't know.
RE: vaapi-sse4: Deinterlacing Testing - lelouch - 2014-05-05
Hi, I have been using this ppa for a while and I must say it is really good. Specially for IPTV.
I have tested IPTV on this xbmc and it works really good. DeInterlacing is good and channel switching time is also fast [about 1-2 secs].
I took my xbmc setup to test an IPTV stream with different vendor. This is where I encountered a weird problem with IPTV. It started taking about 20 -25 secs to switch channels
This is the log - http://paste.ubuntu.com/7398504/
Any help would be really appreciated. Thank you

Did you try "xrandr --output HDMI1 --auto"?
RE: vaapi-sse4: Deinterlacing Testing - alex.ba - 2014-05-06
Hi all,
Quote:xrandr --output HDMI1 --autoNo I did not try yet. The output is: Can't open display. I use an Nuc Hswell with Intel Graphics.
One more question to the splash screen. I installed the package as described on the first page:
Quote:sudo apt-get update
sudo apt-get install plymouth-label v86d
wget http://excyle.nl/plymouth-theme-xbmc-logo.deb
sudo dpkg -i plymouth-theme-xbmc-logo.deb
I also added this line to the grub conf and updated: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
Then I made the reboot.
Now The system starts then I get 2 or 3 lines then the login appears and after about 5 secs XBMC starts. There's no XBMC Logo. However when I shutdown, xbmc closes and the logo appears.
My grub looks like:

# /boot/grub/grub.cfg.

RE: vaapi-sse4: Deinterlacing Testing - CrazyCoder - 2014-05-06
Try this:
DISPLAY=:0 xrandr --output HDMI1 --auto
splash doesn't work because of this bug: https://bugs.launchpad.net/ubuntu/+source/plymouth/+bug/1309617 .

Can someone verify that?

That one:

No idea - but I have seen your post - the last time you posted it.

Usually IPTV streams are multicast. And it happens that stock modem or. router is flooded with packets. This happens especially when switching different providers or. scanning network for new programs (with tvheadend i can kill my modem in few seconds).When i am doing testings i often have to restart the modem i have got from provider. I prefer to convert multicast traffic to unicast (http). This way it works great and if you have a router that can do this (tomato compatible router, dd-wrt did not work well for this thing) then you will also get rid of messing the network stream to the whole subnet. When modem gets flooded it can response slowly or even stops responding to multicast traffic. It is also back-end depended till now best for iptv streams was iptv simple addon (but no recording), tvheadend was ok till 3.5, i have tried VDR but i dont like that i can not mass control icons and xmltv (epg) with it.
