Mencoder stops very early when trying to convert a .mov file into an .avi file
Hi,
I tried to register on the mencoder-users mailing-list but to no avail. So, I think this is probably the best place to talk about my issue: I downloaded this screencast: http://railscasts.com/episodes/199-mobile-devices (55megs, Quicktime RLE) I tried to encode it with Video4Fuze to watch it on my Sansa Fuze (Video4Fuze is just a handy GUI on top of mencoder and avidemux) This failed and gave me a pretty small file, lasting only a few seconds, when the screencast lasts 5 minutes. In addition, while the audio is ok, the video is way way too fast. When I try to launch mencoder using the same parameters used by video4fuze, I get this from mencoder: Code:
mencoder.exe -ss 00:00:00 -ffourcc DX50 -ofps 20 -vf pp=li,expand=:::::224/176,scale=224:176,harddup -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=683:vmax_b_frames=0:keyint=15:turbo:vpass=1 -srate 44100 -af resample=44100:0:1,format=s16le -oac mp3lame -lameopts cbr:br=128 -nosound "C:\tmp\podcasts\Vidcasts\199_mobile_devices.mov" -o brol_fuzed2.avi MEncoder Sherpya-SVN-r29355-4.5.0 (C) 2000-2009 MPlayer Team success: format: 0 data: 0x0 - 0x377187a libavformat file format detected.

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. Flushing video frames. Writing index...

Is this a problem in the source file? Some flags that I should enable in mencoder? Regards, |
