Description

I'm attempting to use the cinepak codec with mencoder. I'm using 1.0~svn33468 on Ubuntu 11.04

I'm attempting to encode a video using the cinepak codec (iccvid.dll). As an example I've been working with this file http://ubuntuone.com/p/iJr/

I converted it to the rgb colourspace in ffmpeg

ffmpeg -i vid.mov -vcodec png -pix_fmt bgr24 outfile.avi

And then tried to run this command in mencoder to convert it to a video using the cinepak codec

mencoder outfile.avi -vf format=bgr24 -ovc vfw -xvfwopts codec=iccvid.dll -oac mp3lame -o outfile_2.avi

When executing that command I get a segmentation fault (output shown below)

why did you convert the file to rgb first ?
encoding works on windows, did not test linux.

It was my understanding that it could only work on videos in rgb. Perhaps I'm wrong about that.

I tried your command (mencoder vid.mov -nosound -ovc vfw -xvfwopts codec=iccvid.dll -o crap.avi) on the same video file and still got the same segmentation fault as before.

I'm now using mencoder version 2:1.0~svn33634 on Ubuntu 11.04

I finally got it working! However, the result shows that there may be an error with the iccvid.dll file that is supplied with mencoder (at least on Linux)

I downloaded the iccvid.dll file from here http://www.dlldump.com/download-dll-files_new.php/dllfiles/I/iccvid.dll/1.10.0.11/download.html and then replaced the one in /usr/lib/codecs with the new one.

I then ran your code again (mencoder vid.mov -nosound -ovc vfw -xvfwopts
codec=iccvid.dll -o crap.avi) and the video encoded and played as expected
