mencoder then pulldown

[lpn1160]

I 've been having some intersting problems, that maybe someone can point out my mistake, if there is one. I use this script to encode some captures I do using streamer with mjpeg. The mencoder script is as follows:

mencoder -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd -vf pullup,softskip,crop=336:464:8:6,kerndeint,expand=352:480,harddup -lavcopts vcodec=mpeg2video:vrc_buf_size=1835:mbd=1:trell:turbo:vrc_minrate=3000:vbitrate=3500:vrc_maxrate=9000:acodec=mp2:abitrate=192:aspect=4/3 -ofps 24000/1001 -sws 9 -nosound -o precint13_1.mpg precint13_1.avi

Afterwards when I try to run pulldown on the file I get this error message:

[larry@localhost cap_scripts]$ pulldown precint13_1.mpg
PULLDOWN - v0.99d, by Hard Code.
[Based on sources by Brent Beyeler (beyeler@home.com)]

SOURCE = precint13_1.mpg, TARGET = pulldown.m2v

- Enabling 2:3 pulldown


File is not an MPEG Video Stream

Anyone know what the problem is??


thanks for ANY help!!

Maybe mencoder is making a program stream and Pulldown requires an elementary stream?

Yes I believe that is the problem. Is there something to put in or take out of my script??

Thanxs for responding

Make an ES with mencoder and then apply pulldown. Then mux the ES with the audio using (say) Imago Muxer.

Use -of rawvideo with mencoder or run mplayer -dumpvideo on the resulting mpeg. Then run pulldown and use mplex, etc. to mux to mpeg.

Thanxs all for the responses, KpeX that did the trick. Thank You

you can also let mencoder's muxer do soft-pulldown directly:
encode as progressive and use -mpegopts format=dvd : pulldown.

P.S. use a recent cvs checkout, or you will have a lot of problems due to the presence of bugs that Neuron2 helped me to fix.
