Ubuntu Lucid - VLC 1.1.1 - no video/sound for dvbt
« am: August 07, 2010, 12:31:32 Nachmittag »
Hi all,

I have the same problem as described here:
The VideoLAN Forums • View topic - VLC 1.1.1 - no video/sound for dvbt

That is - the default VLC 1.0.6 in Ubuntu Lucid works fine - however if I install VLC 1.1.1 from PPA named vlc for Christoph Korn : Christoph Korn, there is simply no audio or video (although nothing crashes, and the LED shines on the device).

I noticed there is a /var/log/mediasrv.log - here are the entries from today, where I have both watched on 1.0.6, and then installed 1.1.1 with a problem, and then reinstalled 1.0.6 back:

Well, hope this helps in identifying what actually isn't working in the new version...

EDIT: The mediaclient version I was using here is:
$ /opt/bin/mediaclient --build
Build date: May  6 2010


Thanks in advance for any help,
Cheers!

Re:Ubuntu Lucid - VLC 1.1.1 - no video/sound for dvbt
« Antwort #1 am: August 08, 2010, 09:56:49 Vormittag »
We just tested VLC and it seems to work fine, however we used the development driver which is as it says under development and will replace the 'stable' driver as soon as all new features are set.

http://www.sundtek.de/media/sundtek_installer_development.sh

you can check the version with /opt/bin/mediaclient --build
Zitat
$ /opt/bin/mediaclient --build
Build date: Aug  6 2010

This driver gets updated very frequently (eg last release is just a few days ago)

Discontinuity Errors are the outcome of a too weak signal here, and only happened until I adjusted the antenna

VLC 1.1.2:



(unfortunately there are some internet connection issues the full screenshot will be uploaded when the connection is fine again).

Failure is a good thing! I'll fix it

Hi Support,

Thanks for the answer, I tried the new driver - but I have exactly the same problem:
$ /opt/bin/mediaclient --build
Build date: Aug  9 2010

$ /opt/bin/mediaclient -D DVBT
Using device: /dev/dvb/adapter0/frontend0
Setting Frontend Properties to: DVBT
Done.

I have noticed that the duration in the lower right corner, never appears in the new VLC 1.1.1/1.1.2:

even if I get the title of the channel displayed in VLC...

Could it be that the driver is not at fault, and I just have an old lib stuck, maybe the one doing the dvb decoding ??!

Well, any other suggestions are welcome, and let me know if I can provide some other logs..

Thanks,
Cheers!

Re:Ubuntu Lucid - VLC 1.1.1 - no video/sound for dvbt
« Antwort #3 am: August 09, 2010, 11:11:09 Vormittag »
the loopback error is no issue, it's something that will be available in newer driver versions.

did you try to use mplayer?

This issue seems to be a signal problem maybe previous vlc versions have been more faulty tolerant.

you can try mplayer using following command (you can use this at the same time as VLC):

cat /dev/dvb/adapter0/dvr0 | mplayer -cache 10240 -

and compare the video quality

additionally you might check the signal strength:
/opt/bin/mediaclient --readsignal=0 -d /dev/dvb/adapter0/frontend0 (it scans until you stop it with ctrl-c)


In case it works well with mplayer try to capture a video (for 30 seconds - this will take 100-200 mb).

cat /dev/dvb/adapter0/dvr0 > /tmp/test.ts

afterwards try to play the video with vlc, if it doesn't work with vlc but with mplayer please upload the video so we can check if the content has some generic issues with VLC.

Hi Support,

Thanks for the speedy answer...

the loopback error is no issue, it's something that will be available in newer driver versions.
Thanks for the info - good to know!


did you try to use mplayer?
Nope, I didn't even have it installed - so now I just sudo apt-get install-ed it..

This issue seems to be a signal problem maybe previous vlc versions have been more faulty tolerant.
Could be, since both VLC 1.0.6 and Kaffeine 1.0-svn3 deal OK with video (but Kaffeine still cannot handle audio on my system)

you can try mplayer using following command (you can use this at the same time as VLC):

cat /dev/dvb/adapter0/dvr0 | mplayer -cache 10240 -

and compare the video quality

Ok, this is interesting - after install (or after I unplug/plug the stick), I try to run the following:
$ /opt/bin/mediaclient -D DVBTUsing device: /dev/dvb/adapter0/frontend0
Setting Frontend Properties to: DVBT
Done.

$ cat /dev/dvb/adapter0/dvr0 | mplayer -cache 10240 -

And it stays and "Cache fill:  0.00% (0 bytes)" all the time until I press Ctrl-C; no window (for displaying video) is raised at all...

Then, I start VLC1.0.6 on a channel which works - and I try to run mplayer "in parallel":
$ cat /dev/dvb/adapter0/dvr0 | mplayer -cache 10240 - 2>&1 | less -omplayervlc.log
While VLC is running, so does mlayer - although mplayer keeps on "jerking" the video (as in playing half a second, then pausing for less than half a second, then playing again etc.. - note though, this is not a powerful PC, and any application showing DVBT uses like 80% of CPU); although the audio seems fine.

If I then close VLC, and leave mplayer running, it will speed play through the remaining video (while audio still runs smoothly) - and as soon as it runs out of frames, the video freezes; and only thing I can do is close mplayer.

The 'mplayervlc.log' captured in such a session is here: http://slexy.org/raw/s2Hqorchp9 (1.5 MB, one month expiry)

If after that, I try to run the mplayer command line again:
$ cat /dev/dvb/adapter0/dvr0 | mplayer -cache 10240 -

Or, in other words, it starts buffering up to 19%, and then it freezes until you press Ctrl-C (and bviously, since it started buffering, now it gives more verbose messages than when it buffered 0%). Repeated callings of this command line hereafter always result with buffering up to circa 19% though not always exact the same (another run may give 19.69%, etc).

additionally you might check the signal strength:
/opt/bin/mediaclient --readsignal=0 -d /dev/dvb/adapter0/frontend0 (it scans until you stop it with ctrl-c)

Here's a brief log, signal seems fine:

In case it works well with mplayer try to capture a video (for 30 seconds - this will take 100-200 mb).

cat /dev/dvb/adapter0/dvr0 > /tmp/test.ts

afterwards try to play the video with vlc, if it doesn't work with vlc but with mplayer please upload the video so we can check if the content has some generic issues with VLC.

Hm... The thing is mplayer will only show any kind of video if VLC 1.0.6 is running along; so I'm not sure whether that could be called 'works well'... However, I tried the above command while VLC 1.0.6 is running, and the resulting test.ts opens very well and plays back in VLC 1.0.6 (in spite of a couple of discontinuity errors)... Though I haven't tested that .ts file yet with VLC > 1.1.1...


Well, I hope this sheds some light on the subject - else please let me know what else I should try...

Cheers!


EDIT - just tried to play the test.ts on a VLC 1.1.1 on a different Ubuntu Lucid machine, and it won't play! So, I uploaded it here

Hope it will help..

Cheers!

Re:Ubuntu Lucid - VLC 1.1.1 - no video/sound for dvbt

ok this sounds like a VLC (maybe ffmpeg) issue then and has nothing to do with the driver.

I looked at the stream and it's an MPEG-4 stream (mpeg-4 is not fully mainstream yet - so we don't wonder that there are some issues at this time since people are still working on it).

If you can capture one more sample (50-100 MB) we can host them on our server so opensource developers can download them quickly.

VLC 1.1.2 (64 Bit) works fine with this video, while mplayer does not.

In order to watch TV we advice to stick with the working VLC version for now, we'll also do some tests with 32bit VLC and put together a summary within the next days. It's mainly a video codec problem.

Hi Support,

Thanks again for the response!

Yup - good to have confirmed that...

I looked at the stream and it's an MPEG-4 stream (mpeg-4 is not fully mainstream yet - so we don't wonder that there are some issues at this time since people are still working on it).

If you can capture one more sample (50-100 MB) we can host them on our server so opensource developers can download them quickly.

Also, had no idea that mpeg-4 is still being worked on; good to know that - another piece (different channel and resolution) is here:

Well, at least its great to finally know the problem is in 'mpeg-ts' and in VLC :) Yup, I'll keep using the old version, as also 1.1.2 has the same problem - and if I get some time, I may try to build the command line VLC from latest git source (which should be around 1.2.0) and see if that has a problem too..

In any case - thanks for the great help !!

Cheers!

For MPlayer we have this report now:
http://www.pubbs.net/201008/mplayer/14086-mplayer-users-qualtiy-issues-with-mpeg-4-danish-dvb-t-clip.html

VLC we still need to check on 32 Bit.
