vdr-xine and AC3 Audio
by Daniel THOMPSON 17 Mar '05

17 Mar '05

Hi Folks I am currently running vdr, vdr-dvd and vdr-xine on one machine and running the xine based display on another machine. Unfortunately the machine running vdr is a bit gutless and decoding AC3 appears to tax it a bit too much (video is smooth until I switch of Dolby in the DVD menu). It is possible to adapt vdr-xine to have xine decode the AC3 stream on the more powerful display machine? -- Daniel Thompson (STMicroelectronics) <daniel.thompson(a)st.com> 1000 Aztec West, Almondsbury, Bristol, BS32 4SQ. 01454 462659 If a car is a horseless carriage then is a motorcycle a horseless horse?

missing (some) sound in 1.3.22
by Tomas Prybil 17 Mar '05

17 Mar '05

Hi all! I just recently moved to 1.3.22 and found as usual new features ;) Parts of the news (for me) is the awaited possibility to pick a specific "sound track". My problem is that some of the channels now are missing sound. The soundpids are all in there. If I remove them they all get properly baack again. The sound of three specific Canal+ channels is gone :( If I remove the AudioLanguages = sve eng from setup.conf the sound gets back again. Any clues? /t

[patch] osdteletext-0.4.2 page render speed up
by Udo Richter 17 Mar '05

17 Mar '05

Hi list, Since osdteletext page drawing is rather slow on my C3-600, I investigated the page rendering speed of osdteletext-0.4.2. Average rendering time is 0.74s, dividing down to 0.11s rendering, 0.45s scaling, 0.09s osd drawing and 0.11s screen update. (numbers might be slightly off due to additional debug output) After a rewrite of the scaler, the scaling is down to 0.1s, speeding up screen update from 0.74s to 0.39s - a noticeable improvement. ;) The attached patch adds the new scaling code.

Problem with text2skin and vdr 1.3.22
by Tero Siironen 16 Mar '05

16 Mar '05

I updated vdr to 1.3.22 today, but text2skin 1.0 doesn't work properly. I have tried with two skins, DeepBlue and Enigma. With 1.3.21 both skins works.

Compiler problems?
by Olaf Titz 16 Mar '05

16 Mar '05

Are there any known issues wrt. different compiler versions? I have tried GCC 2.95, 3.2, 3.3 and 3.4 and most of them produce misbehaving code in one way or another. E.g. with 2.95, the decruft plugin reproducably crashes vdr with signal 9 (yes - 9, no idea where this comes from) and with 3.4 I'm getting segfaults probably due to the xine plugin. Olaf PS. vdr 1.3.22, decruft 0.0.3, femon 0.8.5, osdteletext 0.4.1, xine 0.7.2; glibc 2.3.2.

No picture with Hauppauge Nexus-CA
by Sami Taipale 16 Mar '05

Hi, I can't seem to get a picture out from vdr. I tried with mplayer plugin and it doesn't even open the mplayer window. Also tried with a video cable from the dvb-card's output. That gives me the vdr osd but no tv picture.

[ANNOUNCE] bitstreamout plugin 0.80 (sound loop through sound card)
by Dr. Werner Fink 16 Mar '05

16 Mar '05

Hi, I've uploaded the new verion 0.80 of the bitstreamout plugin. >From the changelog from this morning: - Add nonlinear mp2 loop through S/P-DIF similar to AC3/DTS - Use a frame based mp2 parser for libmad with buffer gard - Make PCM initial wait frames configurable - Remove Z680 option - Remove MP2offset - Add a workaround for broken sub audio header in PS1 payloads - Be smarter in AV synchronization, wait on stable STC value - Make xlist find plain AC3 in PS1 payload even from ORF A note about nonlinear mp2 loop through also from the manual page: [...] Mp2Out (Round,Dither,Nonlinear) Switch for the configuration how to use the MP2 Audio input stream from VDR at replaying a recording or during live viewing from DVB card. The two cases Round and Dither are switches for the resulting linear PCM which its self will be obtained by decoding the MP2 Audio input stream with the help of the LibMad. Dithering leads to a much better sound quality then Rounding it does. The Nonlinear option provides an alternative way how to put MP2 Audio data forward to the A/V receiver. With this the MP2 Audio will not be decoded but send with a simliar method as done for AC-3 or DTS input streams. If and only if your A/V receiver supports the decoding of MP2 Audio stream you may choose this option. But note that for daily use your A/V receiver should support automatic detection of MP2 Audio. Or you have to con- figure your A/V receiver by hand for every change between AC-3, DTS and MP2 Audio input sources. [...] A further note from the manual page about the PCM initial wait frames: [...] PCMinitial [1...12] The numbers of initial PCM wait frames to reset the parser and decoder of your A/V receiver at LiveTV. As larger the number as more your A/V receiver can synchronize but only up to the maxi- mal filling grade of its input buffer. If the value is to large you will hear a large silent pause. You should then decrease the value. A good value for, e.g. Pioneer VSA-E07 is 6. Small val- ues may cause an underrun of the hardware buffer of your sound- card, which can be heard as a short staccato or reset (see Vari- ableIO) initial after a channel switch.

RE: [vdr] Helsinki HTV HD1 and VDR? (HDTV channel)

Ari Huttunen wrote: > No idea. I hope it's something more interesting.. :) I managed to receive and display (vdr + hdtv-patch + streamdev + mplayer) the HDTV test stream when it started on HTV. At that time it was ~10 minutes loop of bits and pieces of different types of shows (euro1080 demo/commercial etc). I tried to receive it again few days back, but it was gone, or changed to another frequency (info of which isn't broadcasted on other channels). Let me know if you find it, but I guess you need a smartcard and paid subscription now... Teemu

[PATCH] vdr-1.3.22 bugfix: delete recording above directory
by Steffen Beyer 15 Mar '05

15 Mar '05

Hello, following problem: when deleting a recording which is followed by a directory in the list of recordings, the directory gets the focus but the help at the bottom of the screen stays unchanged and still shows four options, instead of only "open". It is necessary to update the help row between delete and OSD update, patch attached.
