« am: Dezember 01, 2010, 05:56:42 Nachmittag »
Hi Support,

Zitat
hope this helps

It does, a lot - had no idea 720x576 is standard PAL-BG quality :)

Thanks a lot for the prompt answer!

PS: Thanks for the cmdline suggestion too!

Sundtek MediaTV Pro (Europe) / Options for external (S-Video) input capture
« am: Dezember 01, 2010, 05:30:37 Nachmittag »
Hi all,

I have tried to use the Sundtek MediaTV Pro to do a desktop capture, where I used a König CMP - TELVIEW2 (PC-TV) VGA to TV (composite, S-Video etc) converter.

Basically, I set the desktop to 800x600, and have it cloned on VGA; then I plug the VGA into the König; finally I use S-Video cable as output from the König, and into the Sundtek (via that small cable plug that looks like mini USB, that has S-Video input connector).

Then I open VLC; go to Media/Open Capture Device; enter /dev/video0 for the 'Video device name', and click 'Play'; first I get analog TV static/noise.

Then I do:
$ mediaclient -i
Using device: /dev/video0
ID     | Input
--------------
0000   | Television
0001   | Composite
0002   | S-Video

$ mediaclient -I 0002
Using device: /dev/video0
Setting input: 0002 ... (S-Video) ... done

and then I can see the captured VGA desktop in VLC.

Now, the resolution that is recognized by VLC from the Sundtek stream is 720x576. The original 800x600 looks scaled down to fit in these 720x576, along with a black frame/border. One can 'zoom' from the König device, and thereby use up some of that black frame/border, but I would guess, originally the 800x600 is made into 680x480, and then centered in 720x576.

However, I originally hoped, that this kind of a system would give me 800x600 video - with a quality of an uncompressed desktop screenshot, plus whatever compression the Sundtek has to perform on the signal; and this was important to me, because I don't like fonts heavilly blurred, or with compression artefacts.

As it the scaling down causes fonts to blur - my first question is: is there any way to, possibly, set the capturing resolution of the Sundtek to something else than 720x576 - or is this a limitation of S-Video signal? (in that case, I would hope to set capture resolution to 800x600 in Sundtek, and use the König to 'stretch' the video back again to the original 800x600).

My second question is - what would be the recommended way, for me to capture this S-video stream from Sundtek, directly from the command line (without using VLC)? And hopefully uncompressed (i.e. without additional video compression, than the one coming from the hardware itself)..

Thanks for any suggestions in advance!

Hi Support,

Thanks again for the response!

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

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:

ok, please see:
http://forum.videolan.org/viewtopic.php?f=13&t=79946#p267085

VLC 1.1.1 was very buggy with mpeg-ts
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.

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!

Sundtek MediaTV Pro (Europe) / Re:Ubuntu Lucid - VLC 1.1.1 - no video/sound for dvbt
« am: August 09, 2010, 08:00:51 Nachmittag »
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 -

Exiting... (Quit)

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:
$ /opt/bin/mediaclient --readsignal=0 -d /dev/dvb/adapter0/frontend0

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
http://www.mediafire.com/?qbfqy4h8qpcrlpx
(http://download566.mediafire.com/0a4l9ir8lz7g/qbfqy4h8qpcrlpx/test.ts)

Hope it will help..

Cheers!

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!

EDIT: Just noticed this in mediasrv.log:

Sundtek MediaTV Pro (Europe) / 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!

Hi,

we will add it to the next driver release which we will provide around mid next week (14th April).

Great! My system is not exactly stable, which is possibly why I haven't yet seen the stick turn off after 15s ... quite possible that some of my software does not close right and keeps on claiming the device. So having a command to explicitly turn it off, will save hours of troubleshooting of what could be wrong with my system :)

We are currently investigating alternative options for HDTV channels, currently it either requires an NVidia Graphiccard or a fast PC. Lowering the resolution is not useful since the entire video is encoded in HDTV and rescaling can only be done by postprocessing and adding additional CPU power to the entire process chain. Even if you rescale it the input data is always the same, the USB Stick can handle the HDTV input data without any problem.

I agree with this, which is why I think I haven't explained myself :)

Ok, I assume (but am not sure) that crudely the process goes:
* stick receives a frame of a given resolution
* stick packs the frame, sends it via USB
* PC/driver receives USB packet, retrieves data, unpacks frame
* PC then decodes frame

So, lets say, I'm receiving 400x200 video (just giving some round numbers as example), I would depict it like this:

(400x200 air) => Stick => (400x200 USB) => PC (unpack, decode: 400x200)

Say I can watch this fine, but then I try HD - lets say it is 800x400; then I would depict the process like

(800x400 air) => Stick => (800x400 USB) => PC (unpack, decode: 800x400)

and the bottleneck here is that the PC cannot unpack/decode 800x400 ( I was never implying that the USB Stick cannot handle HDTV input :) )

So, what I was hoping for, is that there would be some driver command, so I would set something like, say, 'hdlowres=1', in which the stick could possibly resample the frame to a lower resolution (say, by sending only every other pixel), and send it as such to PC; i.e.:

(800x400 air) => Stick => (400x200 USB) => PC (unpack, decode: 400x200)

in which case, the PC 'from the start' would receive a 400x200 frame, which it can handle :)

Now, I understand this is very simplified - and probably not how the actual processes occur in the stick; and of course, it depends on whether the stick itself has access to decoded pixels already - I guess it doesn't, but I just wanted to make sure...

Thanks again for the answers,
Cheers!

Sundtek MediaTV Pro (Europe) / Turning off LED diode, and "downsampling" video?
« am: April 08, 2010, 10:11:28 Vormittag »
Hi all,

I am using Sundtek with VLC under Ubuntu 9.10 (strangely in Kaffeine the audio does not work), and it all works fine, except I have two issues:

* When the device is first plugged in, the LED is not flashing. Then as soon as I start watching, the LED turns obviously ON. However, after I stop watching, the LED is still ON, and it remains ON even when I set the PC to suspend. Is there any way to turn off the LED using a separate software command, for example?

* There are some HD channels available, which my PC is unfortunately not powerful to decode completely - and both video and audio drop constantly. What I would like to do in this case, is maybe use some command, so I watch the video at half resolution or less (in the end, what I care for mostly is that the audio is uninterrupted). There is a "half resolution" video command in VLC, but it seems to scale the HD video *after* the full HD has been received, which just hurts performance slightly. Ideally, I'd like to instruct the device to "capture" at half the video resolution, so there is both less data to decode on the PC side and less data through USB. Are there any chances of doing this?

Thanks,
Cheers!
