In order to rip VHS on my rather old box, I purchased a Dazzle
My command is
-f alsa \
-i plughw:0,0 \
-f video4linux2 -tvstd SECAM \
-i /dev/video0 \
-acodec pcm_s16le \
-ac 2 -ar 44100 \
-vcodec mjpeg \
-s 720x576 -r 25 -sameq \
-f avi \
I cannot compress in real-time (CPU too weak). So I grab in mjpeg,
and will reencode later.
It works as expected for short videos. But with a longer video,
ffmpeg is killed after 1h35'50". The output is 13836 MB.
I don't understand why. File too big?
The output file is readable by vlc ou avidemux, but ffplay is
wrong about it:
Input #0, avi, from 'brut.avi':
ISFT : Lavf52.64.2
Duration: 00:07:35.12, start: 0.000000, bitrate: 255030 kb/s
Stream #0.0: Video: mjpeg, yuvj420p, 720x576, 25 tbr, 25 tbn, 25 tbc
Stream #0.1: Audio: pcm_s16le, 44100 Hz, 2 channels, s16, 1411 kb/s
Don't understant why it only "see" 7'35".
