 Posted: Wed Jan 28, 2009 12:29 pm Post subject: MythTV VDPAU .21 backport patch |
 |
|
Mythtv vdpau backport to .21 ebuilds for Gentoo
Advantages are much smoother video playback & much much lower CPU utilization.
This is an ebuild for gentoo that adds vpdau support to Mythtv. The patch backport was done by Jean-Yves Avenard and can be found here:
http://www.avenard.org/files/mythtv-vdpau/
Create a local overlay with path media-tv/mythtv, e.g:
| Code: |
mkdir -p /usr/portage/local/overlay/media-tv/mythtv/
mkdir -p /usr/portage/local/overlay/media-tv/mythtv/files
cp /usr/portage/media-tv/mythtv/files/mythbackend-0.18.2.rc /usr/portage/local/overlay/media-tv/mythtv/files/
echo "PORTDIR_OVERLAY=/usr/portage/local/overlay" >> /etc/make.conf
|
This patch requires at least nVidia drivers 180.29 (see below)
Download the patch & unzip : http://www.avenard.org/files/media/vdpau/mythtv-fixes-glvdpau20744.patch.gz to /usr/portage/local/overlay/media-tv/mythtv/files
Download the ebuild & unzip : http://www.linuxsystems.com.au/mythtv/mythtv-0.21_p20744.ebuild.gz to /usr/portage/local/overlay/media-tv/mythtv/
Then run these commands to install:
| Code: |
cd /usr/portage/local/overlay/media-tv/mythtv/
ebuild mythtv-0.21_p20744.ebuild digest
emerge mythtv
|
Once it is installed open mythfrontend & go to "Setup, TV Settings, Playback & Add a new Playback profile.
Select vdpau for both the decoder & renderer. For the deinterlace method start with Bob 2X which works well on my geforce 8400GS card with 512mb ram.
Depending on your card the other de-interlacers may work as well. Using the patch reduces the CPU load on my AMD sempron 3300 by about 40% when watching HD video.

A new nvidia driver is available so bump your nvidia driver up to 180.29 for this patch. This is how to bump to the current version :
First add x11-drivers/nvidia-drivers to your package.keywords and then bump the driver to 180.29 as follows:
| Code: |
mkdir -p /usr/portage/local/overlay/x11-drivers/nvidia-drivers/
cd /usr/portage/x11-drivers/nvidia-drivers/
cp /usr/portage/x11-drivers/nvidia-drivers/nvidia-drivers-180.35.ebuild /usr/portage/local/overlay/x11-drivers/nvidia-drivers/nvidia-drivers-180.35.ebuild
ebuild nvidia-drivers-180.35.ebuild digest
emerge nvidia-drivers
|
shut down X windows....then:
| Code: |
rmmod nvidia
startx
|
This will re-load the newer nivdia module.

One comment:
It is not a good idea to put customized ebuilds in /usr/portage. With the next "emerge --sync" they would be gone. Put them in a seperate overlay.

The ebuild will be overwritten only if a newer ebuild is released in portage. Otherwise they remain untouched.
edit....updated the howto for overlay

OK, the package.provided method is new to me, but for me it still makes more sense to keep a seperate overlay containing just the 10-20 ebuilds that I really need.

bumped to 20005....more fixes
Tidy up VDPAU::Decode - handle decoder errors more gracefully and be more tolerant of transient corruption in the video stream. |

Not had a chance to try this yet but just emerged it and now have no mythbackend init script...? Will remerge the portage version, save the scripts and then copy them back once merged this version again.

Never had this problem myself. Here is the init script:
| Code: |
#!/sbin/runscript

# Distributed under the terms of the GNU General Public License v2
# $Header: /var/cvsroot/gentoo-x86/media-tv/mythtv/files/mythbackend-0.18.2.rc,v 1.8 2007/06/12 15:49:37 cardoe Exp $
depend() {
# future note for me, backend doesn't have to run on
# same machine as MySQL so should be use
need net
use mysql lircd LCDd
}
start() {
[ -z "${MYTH_VERBOSE}" ] && MYTH_VERBOSE="important,general"
export QTDIR=/usr/qt/3
export HOME=/etc/mythtv
#fixes for bug #101308
unset DISPLAY
unset SESSION_MANAGER
# Work around any strange permissions that may be on these files.
chown -R mythtv /var/log/mythtv/
chown -R mythtv /etc/mythtv/
rm -rf /etc/mythtv/.qt
ebegin "Starting MythTV Backend"
start-stop-daemon --start --quiet --chuid root \
--exec /usr/bin/mythbackend \
--make-pidfile --pidfile /var/run/mythbackend.pid \
--background -- --verbose ${MYTH_VERBOSE} \
--logfile /var/log/mythtv/mythbackend.log
eend $?
}
stop () {
ebegin "Stopping MythTV Backend"
start-stop-daemon --stop --quiet --pidfile=/var/run/mythbackend.pid
eend $?
}

I'm not sure, but this might occur if you fail to copy the files directory under media-tv/mythtv to your portage overlay. The ebuild looks for the init script in ${FILESDIR}"/mythbackend-0.18.2.rc. In any case you could always copy /usr/portage/media-tv/mythtv/files/mythbackend-0.18.2.rc to /etc/init.d/mythbackend.

Thanks!

Ok I have updated the howto with :
cp /usr/portage/media-tv/mythtv/files/mythbackend-0.18.2.rc /usr/portage/local/overlay/media-tv/mythtv/files/
Also bumped it up to version mythtv-fixes-glvdpau20212.patch which contains a few more bug fixes. |

Just rename the ebuild above to mythtv-0.21_p20553.ebuild, digest and emerge.
Worked for me...
<edit>Even better, rename the ebuild as above, download the latest patch from http://www.avenard.org/media/MythTV_%26_VDPAU/MythTV_%26_VDPAU.html, extract it into the files directory, edit the renamed ebuild (line 85) and change the patch name to the one you have just downloaded, then digest and emerge</edit>

bumped to 20658 patch. Yes you can simply rename the ebuild otherwise I have updated to the latest version which is now very stable on my system. The only problem I have is some mkv videos dont play for me using mythvideo but you can play these with mplayers vdpau.
Make sure you read the FAQ:
http://www.avenard.org/media/MythTV_%26_VDPAU/MythTV_%26_VDPAU.html
important to have this in your xorg.conf
Add to your xorg.conf:
| Code: |
Section "Extensions"
Option "Composite" "Disable"
EndSection

Hey col just an FYI (at least this happened to me anyways)
This was the 1st time i saw this article and tried it out but it kept failing until i realized that the ebuild was calling for the previous patch. It's not calling for 20658, it's calling for 20549.
| Code: |
* Cannot find $EPATCH_SOURCE! Value for $EPATCH_SOURCE is:
*
* /usr/local/portage/media-tv/mythtv/files/mythtv-fixes-glvdpau20549.patch
* ( mythtv-fixes-glvdpau20549.patch )
*
* ERROR: media-tv/mythtv-0.21_p20658 failed.
* Call stack:
* ebuild.sh, line 49: Called src_prepare
* environment, line 3587: Called epatch '/usr/local/portage/media-tv/mythtv/files/mythtv-fixes-glvdpau20549.patch'
* environment, line 1710: Called die
* The specific snippet of code:
* die "Cannot find \$EPATCH_SOURCE!";
* The die message:
* Cannot find $EPATCH_SOURCE!
*
* If you need support, post the topmost build error, and the call stack if relevant.

* This ebuild is from an overlay: '/usr/local/portage/'
|
That was the error i kept getting, but was fixed when i downloaded and installed the previous (20549) patch. |

Instead of regressing, why don't you download the latest patch (that the ebuild is looking for) from the link given above and edit the ebuild to look for the latest patch (as shown above)?

Sorry....my mistake. Not only do you need to rename the ebuild you also need to change the patch file name within the ebuild. I have fixed the ebuild for patch #658
you may need to redigest the fixed ebuild:
ebuild mythtv-0.21_p20658.ebuild digest |

BTW for any who are interested, I have this in my gentoo overlay and I have just commited mythtv-0.21_p20658 with the vdpau, hdpvr and
opengl patches to my overlay. This also includes most if not all of the plugins bumped to 20658 as well.
For vdpau in mythtv I added a vdapu use flag. Without this flag the vdapu patch is not used.
I had to mask sandbox-2.0 for this to install for some reason it got an ACCESS_VIOLATION but showed nothing in the log. Reinstalling sandbox-1.9 did away with this issue.
There is also an ebuild for nvidia-drivers-185.18.14 which I use.
[EDIT]A user pointed out that the hdpvr support needed an additional patch to run successfully
http://cvs.mythtv.org/trac/ticket/5604
I added that here:
http://github.com/drescherjm/jmdgentoooverlay/commit/dd5cecefa589a529a6ba656c40f87d02f4454646
I also added a hdpvr use flag to the ebuild (mythtv-0.21_p20658-r1) that will be needed to activate the hdpvr support.
Thanks Jeremy

Same here. I think I updated to 20744 about a month ago and I have been using it ever since.
