Unable to watch TV when recording
by Arnold Ho 16 Feb '06

16 Feb '06

Hi guys, When I start a recording of the current show in VDR, the show stops completely leaving a black screen. The recording plays back fine after I stop it. Is there a setting that I may have overlooked? Thanks, Arnold

I'd like to boost the recorded volume a bit, since it's really low and listening to the file with an MP3 player is almost impossible. Any idea ? Francesco

MediaMVP stable
by Luis Palacios 15 Feb '06

15 Feb '06

Hi all, I'm looking for the most stable version of 'dongle.bin' plus the vdr-mediamvp plugin. I have it working with vdr-mediamvp-0.1.6 and dongle-2.4.23038 but it's a bit unstable, hangs vdr eventually when switching channels My first try was (the latest) dongle-2.5.23242, but this one didn't even work at all. Once selecting a channel the audio sounds then video doesn't appear and then it backs off to the menu. thanks luis

I'm still lost/learning I have found three possibilities for this: 1. ffserver+ffmpeg: http://vdrportal.de/board/thread.php?threadid=17160&sid=&hilight=ffserver+v… I have tried this but with no success :-( If you get this working: Please tell me! 2. xawtv: It can display the decoded picture of your FF-card. That works, but without sound. 3. kvdr: http://www.s.netic.de/gfiala/ It can display the decoded picture of your FF-card, too. That works only on the same machine where the FF-card is located and additionally can control VDR. Very smart solution! The last two ones show, thats possible to get the picture out of /dev/video* at the same time VDR is running.

Converting a radio recording to MP3
by mc8647tv＠mclink.it 14 Feb '06

14 Feb '06

I started to record every day a radio transmission on a vdr box at 1500 km from the place I'm now, and I realize that it is a 100 MB file I should transfer by sftp every day. So I'd like to compress the file and convert it to MP3 directly on the linux box, in order to compress it further. How can I do ? Francesco

Control chars in file names
by Bernd Juraschek 14 Feb '06

14 Feb '06

Hi, for some videos I got directory names containing control chars (I've found ^A and ^B). Sometimes this chars are confusing bash's TAB filename expansion. What this chars are standing for? Should VDR simply remove nonprintable chars in the EPG info used for directory name generation? Greetings, Bernd -- while(!asleep()) sheep++;

how to determine if a digital audio track is beeing replayed
by Thiemo 14 Feb '06

14 Feb '06

Hi, when playing a bit with the mlcd plugin, i came around the question how to find out if the current audio track beeing replayed is a digital track (ac3/dts) or not. There is a method SetAudioChannel() but this only signals left/right/stereo. Also it is currently only called when a user selects the audio channel manually, not on channel switch or vdr startup (not to mention all those plugins that replay something) The detection, if LPCM or digital audio is beeing replayed is already done in cDevice::PlayPesPacket() , so shouldn't we call MsgSetAudioChannel() from there and extend it with "3=digital audio"? On the other hand this would cause some overhead as PlayPesPacked is called every second... Or is there any other proposed method to determine the currently played audio type? cheers, Tim
