    mplayer recording from analog tv card

    hello there!

    I started using linux because it is great system and my old analog tv card is working today (windows 7 and newer are not supported).

    I was using tvtime for watching tv channels but tvtime cannot record so I switched to mplayer.

    For wathcing tv, this command works for me:

    Code:
    mplayer tv:// -tv driver=v4l2:norm=PAL:input=0:amode=1:width=704:height=480:outfmt=yv12:device=/dev/video0:chanlist=europe-west:channel=SE5
    and I would like to record TV to file. So far, the command below is writing to file, but I dont know how to stop recording (kill process is not working because the capture file cannot be then played in any player).

    Code:
    mplayer tv:// -tv driver=v4l2:norm=PAL:input=0:amode=1:width=704:height=480:outfmt=yv12:device=/dev/video0:chanlist=europe-west:channel=SE5 --dumpvideo --dumpfile=/home/testuser/Desktop/filetest.avi
    so if anyone can help me to: record my analog tv to file and

    maybe to use some encoding, because the recorded file is not very small after some time.

    I would like to record for example for 3 hours. and then, automatically turn off the pc.

    Thank your for your help!

    edit: this code captures, audio is good but video is very fast..

    mencoder tv:// -tv driver=v4l2:width=720:height=576:norm=PALutfmt=uyvy:device=/dev/video0:input=0:fps=25:alsa:amode=1:forcechan=2:aud iorate=48000:adevice=plughw.1,0:forceaudio:immedia temode=0 -msglevel all=9 -ffourcc DX50 -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:turbo:vbitrate=1200:keyint=100 -vf pp=lb,scale=640:480 -oac mp3lame -o test.avi

    ok, the problem was solved adding -noskip into the command.

    working full command:

    Code:
     mencoder tv:// -tv channel=0:driver=v4l2:device=/dev/video0:normid=4:input=0:chanlist=europe-west:width=704:height=480:audiorate=44100:alsa:adevice=hw.1:brightness=0:contrast=0:hue=0:saturation=0 -oac copy -ovc lavc -noskip -quiet -vf scale=704:480 -lavcopts vcodec=mpeg4:vbitrate=3000 -o ./vidfile.avi
