Some video files from another partition or volume does not display in some video displays but display on another and crashes on others.

Seem to play on these video players:

  • vlc
  • smplayer
  • gnome-mplayer

Seem to have some issues in these video players:

totem -some videos are play while others not banshee -some videos are play while others not bangarang -few videos are play while others not and it crashes and happens also in home folder of filesystem dragon player -crashes and seem not to display any video and happens also in home folder of filesystem

Why this happens? Is this a bug?

This error occurs on ubuntu 12.04 beta 2.

On ubuntu 11.10, every video display play all the video from another partition or from home filesystem.

Totem and Banshee use a different media backend (gstreamer) than VLC and *mplayer, so it seems possible that you don't have all of the plugins installed for gstreamer. Are you able to play other mp4 files (from your home folder) in Banshee or Totem? –  michaelms Mar 31 '12 at 21:15
    
yes. i can play other files in format mp4 using totem and banshee only on home folder –  user49523 Apr 1 '12 at 19:48

I would not call such a thing a bug if I understood your question right. Some media players just do not simply support all formats. Some players support format A, B and C, while other C, D and E.

Your problem is with codecs. You can download the package non-free-codecs which should solve the problem by

sudo apt-get install non-free-codecs 

If it does not work, download the following too:

sudo apt-get install libxine1-ffmpeg gxine mencoder mpeg2dec vorbis-tools id3v2 mpg321 mpg123 libflac++6 ffmpeg libmp4v2-0 totem-mozilla icedax tagtool easytag id3tool lame nautilus-script-audio-convert libmad0 libjpeg-progs libmpcdec3 libquicktime1 flac faac faad sox ffmpeg2theora libmpeg2-4 uudeview flac libmpeg3-1 mpeg3-utils mpegdemux liba52-dev

the video format for all the video that i was playing is mp4 ..so i think is no due to the format of the video, but not sure.for example i played video1.mp4 but video2.mp4 not play and video3.mp4 also video4.mp4 play and so on(its an example) –  user49523 Mar 30 '12 at 23:07
    
The fact that the ending of the name is mp4 does not mean that the video is in the mp4 -format. So I think that is the problem. Another thing is that your videos may be corrupted. –  Masi Mar 30 '12 at 23:09

I have a similar problem after upgrading from 11.10 to 12.04beta2.

In 11.10 movie-player had no trouble playing mp4s dowloaded from youtube, however these will no longer play in 12.04beta2. This does not appear to be an obvious missing codec problem as I have all the codecs installed (and the files played OK before upgrade). The files will still play on 12.04 using mplayer and vlc.

The problem is present on multiple machines, both 32bit and 63bit.
