  • Audio latency in softdevice and xineliboutput

    I was using the softdevice. But due to a very bad audio latency, I shifted to the xineliboutput and it is now fine.


    My setup is a wintv hvr-4000 card, gentoo linux, and jack audio running all the time. I use the snd-aloop module to interface alsa and jack as first (default) alsa device, so vdr is using alsa, and I get its audio trough the loop audio device and jack to the real sound card..


    In the vdr menu, I try everything to configure the sound, but nothing was helping with the huge audio latency I get. The sound was at least 1/2 second after the video, and this was very annoying. Is it a know issue, or something I missed into the configuration?


    Code
    SOFTDEVICE_VIDEO_OUT="shm"
SOFTDEVICE_AUDIO_OUT="alsa"
SOFTDEVICE_AUDIO_OUT_SUBOPTS="pcm=default#"


    After the installation and configuration of the xineliboutput plugin, the sound is working just fine. I cannot see any visible shift between the audio and the video.


    Code
    _EXTRAOPTS="--local=none --video=vdpau --audio=alsa --remote=37890"


    I try to replace alsa by jack (xinelib support jack), but it didn't worked. The sound was flowing out, but trough alsa, not jack. Is it something I can try that would give me the sound directly trough jack?


    I just see I can get the audio into jack by using mplayer (it is configured to use -ao=jack,alsa in its config file), the remote control is working, but I didn't get any OSD:

    Code
    mplayer http://127.0.0.1:37890


    Is it some way to get the OSD from vdr into mplayer?

  • multi-tuner dvb card

    OK, I get it.


    This is cx88_dvb and the authors are Chris Pascoe and Gerd Knorr. Gerd Knorr is the name that come more often with the cx88 series of files.


    I found than an ebuild for vdr-1.7.30 is available into the zugaina overlay. But I will wait until someone fix the driver.

  • multi-tuner dvb card

    According to an answer Rémi Denis-Courmon gave me on linux-nedia, my 3.4.5 kernel is recent enough. The DVB API version 5.5 is found in kernel versions 3.2 and later.


    I should have said than my vdr version is the last in portage, that is vdr 1.6.0. I hope it is recent enough to support this API, because most of the plugins are failing to compile against the 1.7.27 version due to the xgettext transition.


    For info, both tuners was working fine in kaffeine for kde3, but the new kaffeine is a calamity that is even more buggy than the older and mostly unfinished.

  • multi-tuner dvb card

    Hi,


    I succeded to install and configure vdr on gentoo. It is my first vdr installation, and it look like to work. At least, it work with the first tuner of my card. Vdr use the softdevice client.


    But, vdr only seam to recognize and use the first tuner of my Hauppauge WinTV HVR-4000-HD. The devices are in /dev/dvb/adapter0:

    Code
    # ls /dev/dvb/adapter0
demux0  demux1  dvr0  dvr1  frontend0  frontend1  net0  net1


    frontend0 is the dvb-s tuner and frontedn1 is the dvb-t/c tuner, and I want to be able to use both of them. It is a hardware limitation in that card (among other) that make not possible to use those 2 tuners at the same time.


    When starting vdr, the only error message I get at the console is, when I make udev to create symlinks like /dev/dvb/adapter1/*0 to /dev/dvb/adapter0/*1:

    Code
    * VDR errors from /var/log/messages:
 *   ERROR: /dev/dvb/adapter1/frontend0: Device or resource busy


    I can use mplayer instead of vdr. It work with the symiliks with "mplayer dvb://2@", and without the symlinks by acceding directly the drv1 device after tuning with tzap. When trying to access one of the dvb-t channels from shmclient, it tell me "Channel not available".


    Is it a wy to get the dvb-t (adapter0/frontend1) to work with dvr without to loose the dvb-s input?
