TvcardTest

http://www.linuxtv.org/wiki/index.php/How_to_install_DVB_device_drivers

load driver Update V4L drivers and sudo modprobe cx88-dvb and it all works fine.

We're now going to test the card by viewing some output. For this, we'll need some DVB utilities and a movie player. As everything is so easy with Ubuntu, why not try out both xine and mplayer...? 

 sudo apt-get update
 sudo apt-get install dvb-utils dvbstream
 sudo apt-get install xine-ui 

 mkdir /root/.tzap
 sudo scan /usr/share/doc/dvb-utils/examples/scan/dvb-t/uk-WinterHill > /root/.tzap/channels.conf
 cd .xine
 ln -s ../.tzap/channels.conf

This time xine gives me all sort of problems. Going to http://www.mythtv.org/wiki/index.php/Tzap, but using scan instead of dvbscan (as stated above) I found some channels, but not all. Since I had a channel.conf on my MediaServer (this is the frontend I'm doing) I copied that and could now lock a channel: 

 tzap -r "SVT1"
 using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
 tuning to 626000000 Hz
 video pid 0x03fb, audio pid 0x03fa
 status 01 | signal 6363 | snr 8000 | ber 00003fff | unc 00000013 | 
 status 1f | signal 6363 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK
 status 1f | signal 6363 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK
 status 1f | signal 6464 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK
 status 1f | signal 6363 | snr ffff | ber 00000000 | unc 00000000 | FE_HAS_LOCK

I'm now tying to capture something but gets an empty file. 

 cat /dev/dvb/adapter0/dvr0 > testvideo.mpg

  ls -l
-rw-r--r-- 1 user user         0 2007-10-04 22:45 file.ts

After weeks of struggling with this I finally found out that scan was lying above. At that time I had installed Kaffeine, which at first had the same problem as xine to get any picture. The breakthrough was when I discovered that Kaffeine was able to auto-scan my HVR-1300 card and suddenly it started working. Based on those channels I made my own initial-tuning-data-file for scan (se-Gothenburg-FreeToAir): 

# Sweden - Göteborg FreeToAir
# T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy
T 546000000 8MHz 2/3 NONE QAM64 8k 1/8 NONE
T 786000000 8MHz 2/3 NONE QAM64 8k 1/8 NONE
T 522000000 8MHz 2/3 NONE QAM64 8k 1/8 NONE

Running scan with this made xine also happy 

 sudo scan se-Gothenburg-FreeToAir > ~/.xine/channels.conf

Struggling with HVR-1300

Installing firmware 

  sudo cp -p /lib/firmware/2.6.20-15-386/v4l-cx2341x-* /lib/firmware/

A workaround is loading the modules by hand

  1. modprobe dvb_core
  2. modprobe cx88-dvb

add the

cx88-dvb

to the /etc/modules

No sound in Kaffeine from HVR-1300

Enable multiverse in your sources.list. Then: sudo apt-get install cvs -d libxine-extracodecs

To all of you who have trouble with sound (usually when playing from analog) just use a command like sox to make a bridge between the alsa "card" built in into your capture card and your sound card. This works for me: Code:

$ sox -c 2 -t alsa hw:1,0 -t alsa default

Let's analice it -c 2 means we want to reproduce it on stereo -t alsa means that input and output cards are both alsa hw:1,0 is the name of the device made for your capture card (it may vary just try until you find it, "hw:2,0" , "hw:3,0" etc). default is the name of the output card, usually if you have configured alsa to play multiple sounds that's the correct name, otherwise it may be something like hw:0,0 or hw:1,0 etc. http://ubuntuforums.org/showthread.php?p=3474949

After reading your response, I tried to focus myself on the firmware needed for the HVR-1300 mpeg encoding to works. In fact on my system, the firmware was in the wrong directory. It was inside /lib/firmware/2.6.21, and the kernel module (blackbird?) was expecting to find it inside /lib/firmware. I simply copied the needed file inside this dir, and I have been capable of recording a mpg from /dev/video1:

  1. v4l2-ctl -i 1
  2. v4l2-ctl -s pal
  3. cat /dev/video1 > test.mpg
  4. mplayer test.mpg

Two first lines are usefull for me to select composite input, and pal system.

Without the firmware, only the uncompressed cx88 device will work, the blackbird device will not work without firmware.

You'll need a 'v4l-cx2341x-enc.fw' file with the encoder firmware just like the ivtv driver needs it. Without it, the mpeg2 encoder chip on the board is just sitting idle http://archives.devshed.com/forums/linux-97/hvr-1300-cx88-blackbird-and-mythtv-2176896.html
