Unhappy FFMPEG : recording Television broadcast.


Hi,

I am trying to record television broadcast using ffmpeg. The video is getting recorded and everything is fine.

The problem is the quality of video Vs. the size. The size of the video is about 250 MB for 30 minutes while the quality is still awefully bad. Can anyone help?

v4lctl setchannel S23
ffmpeg -vd /dev/video0 -ad /dev/dsp1 -ar 32000 -b 1000 -r 30 -s 640x480 -y -t 1788 /home/record/recordings/2006-03-14/5/1142274600.mpg

This is the command I used. Also, the video lags behind the audio. Please help me improve quality and compression. Most 30 minute videos I've seen are much smaller than 250 MB and of very superior quality. Is it not possible in TV Tuners?

(its using some saa7134 module for running the card)
