Hi everybody,

Could you please download this little file (less than 512 Kb).
http://rapidshare.com/files/129313759/bug.mpg.html

When i used mediacoder Version 0.6.1 build 4135 to convert this bug.mpg movie to an xvid avi using settings indicated below (in command lines), mencoder crashes.
FYI, when i disabled resizing, mencoder not crashed. I think the crash occurs because it's unable to resize the video.

Thanks you for your help.

Here are the command lines generated by mediacoder :

Under Video Tab, uncheck auto select box next to source. Select MPlayer as source.

Mencoder will no longer crash.

Thank you B!ink for for your help.

I tried, to used mplayer as source instead of mencoder, but i had an another error (error code 013, no file is outputed) a the end of file, even if the source file can be played well by mplayer

Thank you B!ink again for for your help

As i said before i tried the solution you had suggested (mplayer as source), but it failed.

But i tried to use ffmpeg as source and it worked fine, but the encoding is 2 time slower than using mencoder.

For me there is no issue for mediacoder and this topic is closed because the problem has been solved. The issue is only due to mencoder.

Thank you B!ink & Stanley for your job.

Keep an eye on the up-coming updates, it is quote possible the mencoder in a certain update might have the problem solved. The MPlayer/MEncoder folks work very hard.

Thank you Stanley,

I have new clues about this problem.

I tried to add "pp=ha/va/dr" to the mencoder command and mencoder has not crashed.

I used an older version of mediacoder (0.6.1 build 4075) and I found that "pp=ha/va/dr" was generated at this time.

I found that :
1/if any post processing (pp=ci or pp=ha) filter is enabler mencoder didn't crashes.

2/ if no post processing are enabled, the command line should look like that : "-vf crop=720:576:0:0,pp=,scale=512:384:0:0:0.00:0.50"

if command look like "-vf crop=720:576:0:0, scale=512:384:0:0:0.00:0.50", mencoder crashes.

Could you please tell me what do you think about that ? and if it could be taken as a new issue ?

Best regards

Regarding the mencoder.exe issue I just unchecked the auto select boxes but left the choices MEncoder active (did not change to another Source or Encoder).
It seams that the system requires to be told what encoder to select.
After that no problem.
Cheerio.
