Ubuntu Multimedia :: Hauppaage HVR-2200 Second Tuner And Slow Channel Switch?

May 13, 2010

I'm running MythBuntu 10.04 32-bit on an ASUS DualCore Atom + NVidia ION chipset. It's taken me a while to get it all working (still not there yet on the remote!), but there are a couple of glitches with the tuner card.

10.04 appears to have the kernel modules already, so I installed the firmware following linuxtv.org instructions and got it working pretty quickly in MythTV. I've since built the latest stable kernel module and updated the firmware to v4l-saa7164-1.0.3-3.fw which appears to be the latest. Same issues in both cases anyway.

Problem 1: The picture using /dev/dvb/adapter1 breaks up / stutters like there's a poor signal, although it says 90+% and /dev/dvb/adapter0 is rock solid. When I try with mplayer it plays but gives lots of errors on the second tuner, but I guess that's not surprising. Example output:

Code:
[mpeg2video @ 0x3d466c0]ac-tex damaged at 29 102 17% 0% 1.2% 0 0
[mpeg2video @ 0x3d466c0]concealing 45 DC, 45 AC, 45 MV errors
[mpeg2video @ 0x3d466c0]concealing 34 DC, 34 AC, 34 MV errors% 0 0
[mpeg2video @ 0x3d466c0]concealing 7 DC, 7 AC, 7 MV errors1.2% 0 0

Problem 2: Switching channels takes a good 7-10 seconds even on tuner 1. The screen goes black, then you get a tiny fragment of the original channel before the new channel kicks in.

Ubuntu :: Dual Channel Failure & Single Channel Errors

Jun 25, 2011

PC seems to run fine in single channel mode but monitor reports no input in dual channel mode and memtest86+ lists from 1-3 errors per pass in single channel mode. Motherboard (Gigabyte P43T-ES3G) can't be set for the 1.65 volts required by the RAM (2x2 of OCZ3P1333LV4GK PC3 10666). The mobo voltage choices are 1.6 or 1.7 volts. I have tried both and increased the MCH voltage from 1.1 v to 1.2 v, but so far can't get it to run in dual channel mode at all and single channel mode seems to run fine but I still get errors in memtest86+. Also tried optimized Bios settings and loosened memory timings (from 7-7-7-16 to 8-8-8-27 and tRFC 60 to 70) and reset Command Rate from 0 to 2. CPU is Core 2 Quad @ 2.4 Ghz, PSU is rated at 400 watts, Video card is Gigabyte GT220.

Ubuntu Networking :: 'wlan0 Is On Channel -1 But The AP Uses Channel 6' With Airplay-ng?

Jun 29, 2011

I'm trying to crack my wep password just for kicks, but I keep running into the same error. When I try to use airplay-ng for the packet injection, it always gives me the error " wlan0 is on channel -1, but the AP uses channel 6". I've tried setting wlan0 to channel 6 manually, but that doesn't help. I spent a while searching for a solution, but it seemed like each page had a different, usually highly complex solution, that still doesn't work. I have the most recent drivers for my wireless card, and it meets all the requirements. So, is there any solution to this that will actually work?

Ubuntu Multimedia :: TV Tuner Not Working In 9.10 But Is Recognised

Mar 29, 2010

Ubuntu version: Karmic Koala (ubuntu 9.10)I've been fiddling arround quite some time with this card. So far i established the following:

1. Card is supported by drivers already available in kernel (v4l, v4l(2)).
2. Card is recognised by Skype as well as by gstreamer. However gstreamer gives me mostly greeen screen when i test it. no propper picture. both found it on video1 (video0 is webcam).
3. I know it is supposed to work well in Linux URL...instructions are for fedora here.
4. there are quite a few tutorial for this card online (even ubuntu), however they are for older version and most of them consist of getting new drivers installed (which are already included with Karmic).

TV Time - blank screen - it is trying to get video from video0 device, which is webcam. i can not set it to use video1 instead as when i click in the menu to change input nothing happens.VLC player - i select use device and set it to V4l or PVR. in both cases the programme itself switches to video0 and turns on my webcam. Nothing else happens. I also installed iv-tv including all necessary libraries and dependancies - as suggested as solution to similar model of card. Didn't change anyhting. it's basically the only thing that is not working yet (most other things i already solved-sort of). I am also interested why the programmes keep switching automaticly to video0 for input when i clearly state to them to use video1?!If this can not be solved can anyone suggest another cheap TV tunner that "just works" in Ubuntu (including remote control)?! I have a big monitor and i think i could use it as TV instead of getting a new TV....

Ubuntu Multimedia :: Get Ati TV Wonder 650 Tv Tuner Work On Karmic

Does anyone know of any way to get this thing to work on Karmic? Just to be able to watch TV, not even to record? I can't seem to get it to recognize it. lsusb just shows:

Code: Bus 001 Device 006: ID 0438:b003 Advanced Micro Devices, Inc. but it doesn't show up in dev/video0 or anything like that, and I don't know of a program which will play it. I don't really have the money to go out and buy another tv tuner, so I really would like to get this one to work, or else I'm going to have to switch to windows

Ubuntu Multimedia :: Compro M1F TV Tuner 10.10 No Sound

Nov 6, 2010

I have a Compro Videomate M1F TV tuner card (internal PCI). After installing ubuntu 10.10 I noticed my card was not recognized and tvtime showed no image no sound. After a Google search, I found differente threads and I tried the following: I've created saa1734.conf in directory /etc/modprobe.d (with administrative rights) with these lines:

Quote:

alias char-major-81 videodev
alias char-major-81-0 saa7134
options i2c-algo-bit bit_test=1
options saa7134 card=99 tuner=59 secam=dk
options tuner secam=d

After that, I rebooted the computer and after starting tvtime, I can see all the tv channels (great) but I have No SOUND and I don't know how to deal with that and couldn't find a solution.I know there is a problem with OSS not being supported anymore or something like that and I am a bit confused.

Ubuntu Multimedia :: Webcam And Tv Tuner Don't Work?

Jul 18, 2011

My tv tuners works under vlc only, my webcam only works in vlc and xaw tv, I tried skype and it didn't detect either one. However in Puppy Linux both of these worked flawlessly, they were both detected in skype. here's v4l-info.

Code:
### v4l2 device info [/dev/video0] ###
general info
VIDIOC_QUERYCAP[code]....

There is also a /dev/video2 but when I try v4l-info /dev/video2 the terminal hangs and I have to close it out. Also I've tried.

Code:
LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so skype

It didn't work. Also gstreamer-properties doesn't start. I don't know if it's related or not.The first was that I couldn't even get it to boot off of the cd in order to install it, I had to use a usb.

Ubuntu Multimedia :: Setup Tv Tuner Card With Vlc?

Sep 1, 2011

I have a sabrent tv tuner card (tv-pcirc). I want to use it in vlc but don't know how to change from the composite source to the tuner source and from there don't know how to change channels (is there a program that generates channels.conf for analog channels?) It would also like to know how to record a certain channel for a certain period via the telnet interface. Another thing I would like to know is how to set up the remote with it, because the audio is very soft and I would like to raise the voume.

My card is using card=42 tuner=43.

Ubuntu Multimedia :: ATI All-In-Wonder Radeon 9000 TV Tuner No Sound

Mar 14, 2010

I have an ATI All-In-Wonder 9000 AGP4x video card with TV tuner function. I following the description on [URL] where I found a how-to for enabling TV tuner. The tuner works in xawtv and avview but without sound. I plugged the cable in from tuner to my sound card and try to increase volume and/or enable mute on/off but nothing to hear. The sound card line-in input works correctly, because when I attaching my MP3 player I hear sound over the sound card. I think maybe have a register accessing/writing error which handle the TV Tuner sound chips to turn on/off. (the tuner works correctly in Windows XP). I'm using Ubuntu 8.04.4 LTS with x86_64 (amd64) actually. The lspci output for Video Card:

I have tried kaffine and myTV, but ultimately I would like to get this device working with my mythtv installation.I have followed alot of threads suggesting updated firmware etc but still no luck.

Ubuntu Multimedia :: Tv Tuner Won't Work After Unplugging And Replugging?

Oct 22, 2010

After much effort I got mythtv to work on my HP TouchSmart. Then I decided to install it on my laptop before I forgot all the troubleshooting tricks.So I unplugged my Hauppauge WinTV-HVR 850 from the TouchSmart and plugged it in the laptop. I was successful getting mythtv running on the laptop so I returned the tv tuner to the TouchSmart.Much to my dismay, mythtv no longer worked on the TouchSmart. I moved the tuner to the laptop again to see if mythtv worked. It didn't. Apparently, the act of unplugging the tuner and plugging it back in broke something.

For usb hard drives and cameras, an icon appears on the desktop that allows me to right click and choose to safely remove the device. I had no idea that unplugging a usb device without such an icon would cause any problems.Initially, the problem seemed to be with mythtv as I was able to successfully execute the following commands:

Code:
scan -x0 /usr/share/dvb/atsc/us-ATSC-center-frequencies-8VSB
mplayer dvb://WTVF-HD

Ubuntu Multimedia :: How To Configure INTEX TV Tuner Card

Dec 24, 2010

I have INTEX TV tuner card. i'm trying to configure in ubuntu for tvtime. The card has the saa7130 or saa7134 philipse chipset.

lspci | grep -i saa713

output:

Code:

00:0a.0 Multimedia controller: Philips Semiconductors SAA7130 Video Broadcast Decoder (rev 01)

after the installation, the card was detected and /dev/video0 was created but dmesg indicated that the card is not among the ones listed as supported and since card did not have EEPROM, the card was not up and running right away.i have edited /etc/modprobe.d/tvcard.conf and added options saa7134 card=3 tuner=14

Code:

$sudo nano /etc/modprobe.d/tvcard.conf

added:

Code:

options saa7134 card=3 tuner=14

Then CTRL+X to exit

still it did not work. tvtime would always say no signal and tvtime-scanner never picked up any channels. then i followed instruction given by rsramkee [URL]. edited saa7134-cards.c and deployed new kernel linux-2.6.36.2 with changes.i rebooted machine to windows selected one channel in tv tuner software of windows, again rebooted machine to ubuntu (i have dual boot windows XP and ubuntu 2.6.35.23). tvtime able display video of channel that is selected in windows OS (No sound), but not be able to tune any other stations.In mplayer able display video of channel that is selected in windows OS with sound.

command:

Code:

mplayer tv:// -tv driver=v4l2:chanlist=us-cable:alsa:adevice=hw.0,1:amode=1:audiorate=48000:forceaudio:volume=100:immediatemode=0:norm=PAL

i followed instruction given by http://linuxtv.org/wiki/index.php/Saa7134-alsa to set up sound. loading the loopback module with the command:

$ pactl load-module module-loopback

Now tvtime able display video of channel that is selected in windows OS with sound, but not be able to tune any other stations. Not be able to tune any stations.dmesg output:

Code:

[ 1320.568603] saa7130/34: v4l2 driver version 0.2.16 loaded
[ 1320.568697] saa7130[0]: found at 0000:00:0a.0, rev: 1, irq: 18, latency: 32, mmio: 0xdffff800
[ 1320.568737] saa7130[0]: subsystem: 1131:0000, board: LifeView FlyVIDEO3000 [card=2,insmod option]

[code]...

i'm not be able to tune any stations using tvtime and xawtv. if channel is not selected in windows OS for more then 1 hour then tvtime displays message no signal, same message in tvtime-scaner (No sound).
