[MPlayer-users] failing to encode NTSC movies

[Dominik Szczerba]

  Hi,

After a week of trying I still have problems encoding a few of my NTSC 
dvd's and/or vob's. They are all reported by mplayer -v as 29.97 fps 
movies and play just fine (OK, one dvd gets stuck in the middle, but 
let's leave it for now, the other plays fine).

I am doing things like:

nice -n 19 mencoder -v -oac mp3lame -lameopts cbr:br=128:aq=2 -ovc 
frameno -ofps $FPS -o frameno.avi -vob
subout $TITLE -aid $AID -sid $SID ./stream.dump

with different tries on $FPS

and I get (just a sample of errors):

(...)

... and the output file is truncated, it reports:

Video stream:    0.766 kbit/s  (95 bps)  size: 196900 bytes  2055.064 
secs  49249 frames
Audio stream:  128.000 kbit/s  (15999 bps)  size: 32889216 bytes  
2055.576 secs

which is wrong.

I tried the above also with fps=23.976, the same.

Another try on a different DVD:

DEMUXER: Too many (4096 in 8287307 bytes) video packets in the buffer!
Maybe you are playing a non-interleaved stream/file or the codec failed?
For .AVI files, try to force non-interleaved mode with the -ni option.
ds_fill_buffer: EOF reached (stream: audio) 
a52: CRC check failed!

I tried also with/without -ni option and/or -nocache option (I have 
cache by default in my config)

Would you please help me out of this puzzle? Is it a Region Encoding Demon?
