SAA7134 tuner card and VLC

Postby byteworks » 25 Oct 2005 17:23

Ok, I'm struggling with this for a few days now. Tuner card is Lifeview 3000, SAA7134 based, I managed to install it and works with xawtv and tvtime.
After hard tries I succeded to compile VLC on Slackware 10.2 with 2.6.1.3.4 kernel, here is configure (VLC 0.8.2):

Code: Select all

./configure --enable-flac --enable-theora --enable-esd --enable-arts --enable-alsa --enable-qt --enable-kde --with-ffmpeg-tree=/opt/ffmpeg-20041113 --enable-skins2 --enable-vxwindows --with-wx-config-path=/opt/wxWidgets --enable-v4l --enable-dvdnav
But no luck opening tuner card, here is VLC output:

Code: Select all

[00000239] main playlist debug: adding playlist item `v4l://' ( v4l:// ) [00000239] main playlist debug: creating new input thread [00000246] main input debug: set input option: v4l-vdev to /dev/video0 [00000246] main input debug: set input option: v4l-norm to 3 [00000246] main input debug: set input option: v4l-frequency to -1 [00000246] main input debug: waiting for thread completion [00000246] main input debug: thread 3032587184 (input) created at priority 0 (src/input/input.c:230) [00000246] main input debug: `v4l://' gives access `v4l' demux `' path `' [00000246] main input debug: creating demux: access='v4l' demux='' path='' [00000247] main demuxer debug: looking for access_demux module: 1 candidate [00000247] v4l demuxer debug: V4L device LifeView FlyVIDEO3000 5 channels 0 audios 48 < w < 720 32 < h < 578 [00000247] v4l demuxer debug: invalid width 0 [00000247] v4l demuxer debug: invalid height 0 [00000247] v4l demuxer debug: setting channel Television(0) 1 tuners flags=0x1 type=0x1 norm=0x0 [00000247] v4l demuxer debug: will use 720x578 [00000247] v4l demuxer debug: v4l device uses brightness: 43176 [00000247] v4l demuxer debug: v4l device uses colour: 39218 [00000247] v4l demuxer debug: v4l device uses hue: 32896 [00000247] v4l demuxer debug: v4l device uses contrast: 43346 [00000247] v4l demuxer debug: v4l device uses frame size: 624240 [00000247] v4l demuxer debug: v4l device uses chroma: I420 [00000247] v4l demuxer warning: I420 refused [00000247] v4l demuxer error: chroma selection failed [00000247] v4l demuxer error: cannot open audio device (No such device) [00000247] main demuxer warning: no access_demux module matching "v4l" could be loaded [00000246] main input debug: creating access 'v4l' path='' [00000249] main access debug: looking for access2 module: 4 candidates [00000249] access_file access warning: cannot stat() file `' (No such file or directory) [00000249] main access warning: no access2 module matching "v4l" could be loaded [00000246] main input error: no suitable access module for `v4l://' [00000246] main input debug: thread 3032587184 joined (src/input/input.c:386) [00000239] main playlist: nothing to play
I searched a lot for info onwhat I missed, but seems I am to a dead stop for now. Can anyone help me please?

I am also having difficulties getting VLC to open/record a stream from my TV card. (SAA7134 Philips Semiconductors)
If i open File->Open Capture Device and set Video Device to /dev/video0
In advanced i click Save and in the settings i select "Play locally" "File" and under encoding i just turn on video and audio encoding.

Once i am done i click ok and VLC opens, but doesnt show anything or play any sound. If i then open TV time, i get an echo. If i leave this running for a few minutes and then turn off TV time and close VLC i then open the file that was saved and it appears to have recorded audio, but doesnt have any video.

any suggestions to record this in a better way and get video would be much appreciated. i've almost pulled out all my hair tonight

I can watch TV like that:

vlc -vvv --color v4l:/dev/video0:norm=0:channel=1:size=320x240

channel=0 - TV
channel=1 - Composite
channel=2 - S-VIDEO


Only one program can read from capture card(TV card) in one moment. If you watch TV on tvtime, and you open vlc, TV stops.

How do I configure VLC to change channels on my STB using this card SAA7134 remote control option?

Hi, I have the same problem
v4l demuxer error: chroma selection failed

I have a Smart TV PCMCIA car with a saa7134 chipset. I cannot use vlc to transcode and then broadcast over the internet the Composite signal which is connected to a camera which is placed on top of blackbird nest in my garden. A female blackbird is nesting 4 eggs there and I wanted to broadcast a video stream about it before the eggs hatch in a few days time.

It is strange, I can see the video stream in tvtime and I can transcode and record videos with ffmpeg, but in vlc doesn't work :-( I always get this chroma selection failed ...

I have tried to record with ffmpeg and broadcast the file while ffmpeg is recording but vlc shuts down after a little while.

I have been looking in this forum today, it looks like there is no solution ... If anyone can shed some workaround or hint a solution, I shall appreciate.

I had the same error and fixing the chroma error was actually a size error if I specify the parameter :size=640x480 it all works! Great. Now I have a streaming issue but I need to transcode to make it work...

hope that help people with the same issue.
