[MPlayer-users] Problem copying MPEG4 AVC video.
Louis Tim Larsen
I've upgraded to the current development version of Ubuntu 12.04 x86_64.
I use the current version of mencoder available in Ubuntu 12.04 which
is: MEncoder svn r34540
I try to copying some video with this command (to change the start time):
mencoder input.mpg -o output.avi -ovc copy -oac copy -force-avi-aspect 16:9
But when I try to play the output-file in Totem 3.0.1 it only plays the
audio and failing to playing while searching for a video/x-avi-unknown
decoder. VLC 2.0.0-4 also only plays the audio.
If you check the attracted file you can see that it's like video drops
all frames when it copies the video. I think I have all needed plugins
so I don't understand this.
I've tried with Mencoder 1.0~rc3+svn20090426-1ubuntu16.1 on Ubuntu
10.04, Mencoder 1.0~rc4.dfsg1+svn33713-1 (from repo) and the daily PPA
version in Ubuntu 11.10 with the same results.
If I transcode the video with lets says x264 and ac3 the output-file
plays fine in both Totem and Totem. However I don't want to transcode 2
hour of video if I only want 20 minutes of it.
If I try to transcode the input-file with HandBrake 0.9.6 it's feels
like every second frame is missing since the audio becomes very lackey.
I've tried to look at google and some forums but couldn't find a
solution. I would be happy if someone could help =)

This is an intentionally broken version of MEncoder that afaict is
not supported here, please either test by compiling yourself or
try ffmpeg -i input.mpg -acodec copy -vcodec copy output.avi
(also current git head, both FFmpeg and MPlayer do not have to
be installed to work, i.e. you can test from the build directory).
