Are you trying to visualise the raw data? If so, try something like this:

$ hacktv -m pal -t uint8 -s 13500000 -o - test | mplayer -demuxer rawvideo -rawvideo fps=25:w=864:h=625:y8 -

Ok And The Size Other Mode, What Size Frame To Correct Read, NTSC ...

fsphil commented 5 years ago

Look for the frame rate and full frame resolution in the hacktv output:

$ ./hacktv -m ntsc -t uint8 -s 13500000 -o /dev/null test
Video: 715x480 29.97 fps (full frame 858x525)

To view the raw output for the above in mplayer, you need to use 858x525 and 29.97 fps:

$ hacktv -m ntsc -t uint8 -s 13500000 -o - test | mplayer -demuxer rawvideo -rawvideo fps=29.97:w=858:h=525:y8 -
