خود درگیری بین سیستم - وب کم - کارت تی وی

[سید محمود رضا سجادی]

سلام دوستان
بالا خره به من هم کارا تی وی - مودم - و وبکمم راه افتاد
البته به لطف اوبونتو ۹.۰۴ که معلوم نیست چسکارش کردند که اینقدر باحال شده و همه چی رو میشناسه

گویا این کرنل هجدیدش معجزه کرده

اصل مطلب

من اشتباها اول کارت تی وی رو نصب کردم و بعدش وب کم رو
وبکم شده /dev/video1
و تی وی شده /dev/video0

camorama می خاد وبکم رو روی /dev/video0 پیدا کنه و شکست می خوره و خود به خود بسته میشه
تمام برنامه های پخش تی وی و رادیو هم نمیدونم چرا - اما تا باز میکنم سیستم هنگ میکنه و باید ریستش کنم!!!!!

لطفا یکی کمک کنه
کلی زوق کرده بودم که تی وی دار شدم

من از سایت
http://www.avermedia.com/avertv/Support/Download.aspx?Action=search&Kind=APDriver&interface=3&signal=3&keyword=linux
تنها درایور X86 ای که از اف ام پشتیبانی میکرد رو دانلود کردم یعنی
http://www.avermedia.com/avertv/Support/DownloadCount.aspx?FDFId=2600

حالا هم یه کارایی کردم
مثلا برای حل مشکل وبکم دستور زیر رو اجرا کردم

کد: [انتخاب]

camorama -d /dev/video1
برای حل مشکل تی وی هم هرچی فایل توی سایت و داکیومنت هاش بود زیر و رو کردم
کد های زیر رو پیدا کردم

========================
MPlayer
========================

MPlayer is a multimedia player capable of supporting variety of media sources.
In this case, MPlayer can be used for watching NTSC/PAL/SECAM/DVB-T TV programs.
TV audio is supported by MPlayer directly.

Ubuntu 7.10, 8.04 and 8.10 is tested with MPlayer and works with our driver.
To use MPlayer in Ubuntu, please install by doing the following at the terminal
window:

$ sudo apt-get install mplayer

To watch NTSC TV programs, for example, please do the following:

$ mplayer tv:// -tv driver=v4l2:device=/dev/video0:alsa:adevice=hw.1,0:amode=1:audiorate=48000:forceaudio:volume=100:immediatemode=0:normid=12:freq=409250:outfmt=YUY2


To watch PAL TV programs, for example, please do the following:

$ mplayer tv:// -tv driver=v4l2:device=/dev/video0:alsa:adevice=hw.1,0:amode=1:audiorate=48000:forceaudio:volume=100:immediatemode=0:normid=0:freq=147250:outfmt=YUY2


To watch DVB-T TV programs, please fist use "dvbscan" to perform channel scan and copy the resulting program list into
~/.mplayer/channels.conf. Second issue the following command:

    $ mplayer dvb://BBC

In this case there must be a program name called "BBC" in ~/.mplayer/channels.conf.

Please also note that MPlayer provides a "slave" mode in which commands can be issued to mplayer to change
TV channel and other settings as well. A list of commands can be obtained by running the following commands:

    $ mplayer -input cmdlist


For detailed usage of MPlayer, please refer to the official MPlayer website:

http://www.mplayerhq.hu

For detailed information of "dvbscan", please refer to the following website:

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

اما تصویر ندارم
یعنی همش برفک نشون میده

مشکل ازکجاست؟
چجوری باید کانال ها رو تنظیم کنم؟
