attached you'll find an updated patch for VDR-1.5.10. It replaces the formerly patch for VDR-1.5.9.

could you seperate the patch into H.264 and DVB-S2 parts again? I use DVB-C with it here and do not want to upgrade to drivers with DVB-S2 support.

I've removed the DVB-S2 part from the original patch. The result is attached. Please give it a try.

How about version that allows reception of dvb-[t,c,s] and dvb-s2? I did test with the instructions found from: http://www.vdr-wiki.de/wiki/index.php/OpenSuSE_DVB-S2_-_Step_by_Step_Install...

but... when tuning to dvb-c channels, i get message saying something like "channel not available".

Of course one can have separate vdr instances on each cards by using -D option, but that's not the best choice. br.

Thanks. It does work as expected. I am still not able to play H.264 content on my Core2Duo 6850 (3.0 GHz) though. My nvidia graphics card 8600 does not seem to support xvmc so I have a lot of dropped frames and lots of block artefacts which seem to be caused by the stream (ffmpeg always says something about cabal(?)). Can I transcode the records into something playable under windows? pes2ts does not seem to work.

Cheers Jan

Try the patch at posted at http://www.vdr-portal.de/board/thread.php?threadid=50139&page=32 from Reinhard, which will solve most of the performance problems. Unfortunately, transmissions using interlaced pictures+spatial direct mode still do not seem to work right and may cause major performance and stability problems.

Awesome, that works like a charm even with deinterlacing on. I will try xine-0.8.0 tonight. Keep up the nice work Reinhard!

Hi,

I tried the patch yesterday on my desktop computer: -

2.13Ghz Intel Core 2 CPU 2Gb RAM Nvidia 6200LE PCI-E graphics card 400Gb IDE (not SATA) hard disk Skystar 2 DVB-S Latest Ubuntu with xorg Latest NVIDIA Drivers Hooked up DVI -> HDMI on a Pioneer 43" plasma TV at 720p (native resolution of the panel = 1024x768) and using 32bpp on the desktop. vdr-1.5.9 with the earlier h264 patch (I didn't see the seperated patch for 1.5.10 yesterday) xine-lib-cvs

The only test channel I could try it on at the moment is the BBC HD service on Astra 2 which is FTA, DVB-S and mpeg4 (MBAFF). Used tvtime Greedy2Frame deinterlacer in xine.

The picture was very good, but there was dropped frames that xine reported and the stuttered on occassion and then ran very quickly to catch up. Playing around with the settings in xine (setting threads to 2 etc) didn't really make much difference. However, for the first time I've spent playing with this I was impressed with the picture quality out of VDR. Top reported that the CPU was ~40% idle so I don't know why I saw dropped frames...

One other thing I noticed though was when using XVMC (-V xxmc) to view normal MPEG2 channels the VDR OSD looked terrible (very blockly looking) and playing with the settings in the xine plugin did not make it better. Any recommendations on improving this? When using MPEG4 (i.e. software accel) the OSD was fine.

Any thoughts on this anyone and/or Reinhard?

Cheers

Hello Reinhard

it's interesting - is there some opinion from VDR's users about this path ? Which h.264 dvb-s2 channels is it possible to watch really ? What about CPU's load during this ? which hardware (dvb-s2 card, cpu, graphic card) use ?

regards Igor

Frame duration wasn't set at all in xine-lib for this case. xine-lib-1.2 contains now a fix for this issue. The fix is part of vdr-xine-0.8.0's xine-lib.patch for xine-lib-1.1.8, too.

xxmc's OSD support allows only 16 colors. I assume, you've enabled font antialiasing in VDR, which requires much more than 16 colors. This is the case for hardware accelerated MPEG2 decoding. For H.264, xxmc falls back to xv where there is no such limitation.

You may also want to try to choose unscaled OSD in vdr-xine's setup menu, which renders the OSD on top of the video image, using libX11. It is therefore not limited to 16 colors but doesn't support OSD transparency at all.

Bye.

Where can I find xine-lib-1.2?

xine-lib-1.2 is only available from the hg repository. Please follow this guide:

http://www.vdr-wiki.de/wiki/index.php/OpenSuSE_DVB-S2_-_Step_by_Step_Install...

Although not required, I'd suggest you to use vdr-xine-0.8.0 too (see other thread about fixes).

Bye.

OK I have lib-1.2 and vdr-xine-0.8.0 humming along. Image very clean and CPU usage is down another 5%. I will see if the new version of openchrome and libXVmc fixes something (CPU was 15% when I started this VDR journey). Zaps fast. Locks solid when right clicking to get the xine menu...

Is there any support for h.264 decoding in any of the linux support libraries for the CN700 now?

Otherwise I'd assume that XvMC was not in use when not doing mpeg2 decoding.

Hi Reinhard,

I have downloaded and installed the latest CVS of ffmpeg and xine-lib as well as installing the latest vdr-xine-0.8.0. I again followed the general compilation instructions at the Open Suse DVB-S2 instructions page.

I have just tried it on BBC HD (Astra 2 - H264/MBAFF) as well as HD2/5 (Astra 3 H264/???) and I get video jumping every 2 seconds. Here is the [clipped] output from xine (verbose=3): -

I don't get video jumping on MPEG 2 pictures, but I do get the video_out "too old" messages.

When the video jumps, the whole of VDR seems to lock up, i.e. you can't move the menu selection on the OSD until the video restarts.

Any ideas - or am I hitting some kind of hardware bottleneck here (dual core 2.13Ghz, 2Gb RAM, IDE disk, NVIDIA 6200LE PCIe graphics @ 720p)? Both cores are idle @ around 40%: -

The picture was very good, but there was dropped frames that xine reported and the stuttered on occassion and then ran very quickly to catch up. Playing around with the settings in xine (setting threads to 2 etc) didn't really make much difference. However, for the first time I've spent playing with this I was impressed with the picture quality out of VDR. Top reported that the CPU was ~40% idle so I don't know why I saw dropped frames...

Frame duration wasn't set at all in xine-lib for this case. xine-lib-1.2 contains now a fix for this issue. The fix is part of vdr-xine-0.8.0's xine-lib.patch for xine-lib-1.1.8, too.

...

One other thing I noticed though was when using XVMC (-V xxmc) to view normal MPEG2 channels the VDR OSD looked terrible (very blockly looking) and playing with the settings in the xine plugin did not make it better. Any recommendations on improving this? When using MPEG4 (i.e. software accel) the OSD was fine.

xxmc's OSD support allows only 16 colors. I assume, you've enabled font antialiasing in VDR, which requires much more than 16 colors. This is the case for hardware accelerated MPEG2 decoding. For H.264, xxmc falls back to xv where there is no such limitation.

You may also want to try to choose unscaled OSD in vdr-xine's setup menu, which renders the OSD on top of the video image, using libX11. It is therefore not limited to 16 colors but doesn't support OSD transparency at all.

Is there a special reason why you use -V xshm and not -V xv? The later would do colorspace transformation in hardware.

I was just changing settings - I did have xxmc on, but it didn't make any difference.

Please give the patch on the below mentioned site a try. Your recording (which uses only interlaced frames) plays properly here when I play it at 50 % of normal speed (my PC simply isn't fast enough for realtime decoding).

That has fixed it - BBC HD and HD2/5 (Astra 3) are now playing smoothly! It is so much better!

Now I have noticed another problem - there is a strange "fuzz" effect (like tearing, but not exactly the same) on some broadcasts and not on others. At first I thought it was the graphics setup on fast panning, but this is not the case - it affects static images also. I saw this on BBC HD and HD2/5. I managed to capture a snippet of the BBC HD preview that demonstrates this - it's very strange because clips before and after this preview snippet were fine again so it must be something to do with this particular HD recording as part of the preview...

Here is a link to a short recording (26Mb) demonstrating the problem: -

Thanks for your help and assistance Reinhard - I read the thread on gmane.comp.video.ffmpeg.devel with interest.

I patched ffmpeg and did a make && make install and the recording is still the same on my system. Do I have to re-compile xine-lib?

I have recompiled ffmpeg svn with this patch, and xine-lib-1.2 (there semmes to be included) and also my vdr which now segfault when I try to tune to BBC HD :

That's with OSD display mode : Blend scaled Auto, with X11 overlay it don't crash (but that's not nice at all...).

By the way there is another annoying bug with xine-lib : if you have a timer set, and VDR want to powerdown, but it can't die to some external reason, you can't control it anymore :

#0 0x000000305440deef in waitpid () from /lib/libpthread.so.0 #1 0x00000000004bfb82 in SystemExec ( Command=0x2aaaae9ee0c0 "sudo /usr/local/bin/vdrpoweroff.sh 1194037200 121229 317 "C'EST PAS SORCIER" 1", Detached=true) at thread.c:511 #2 0x00000000004ad2df in cShutdownHandler::CallShutdownCommand (this=0x7275c0, WakeupTime=1194037200, Channel=317, File=0xfecdec "C'EST PAS SORCIER", UserShutdown=<value optimized out>) at shutdown.c:129 #3 0x00000000004ad8ac in cShutdownHandler::DoShutdown (this=0x7275c0, Force=false) at shutdown.c:247 #4 0x00000000004c962b in main (argc=14, argv=0x7fffcd756e48) at vdr.c:1062

Maybe the bug don't come from xine-lib directly, but without xine-lib it doesn't appear.

Thank,

The new libxine patch should fix this bug.

Great, thank !

Maybe I'll have a look at it tomorrow.

Meanwhile, you could have a look at this issue with this gdb command:

thread apply all bt

It'll tell you the backtrace for all threads.

Oops, with the new patched ffmpeg/xine-lib-1.2/vdr-xine it don't segfault (but I still can't access my VDR after a "shutdown try".

Thank you very much :-)

Sorry wrong thread!
