like the logs said, ffmpeg plugin is not found. Check it is present in your module directory (cf .gpacrc in $HOME directory)

[Athira]

The .gpacrc file shows:

gm_ffmpeg_in.so=Invalid Plugin

How to fix this?

[Jean Le Feuvre]

remove this line, save the config file, launch the player and check the error(s) it will give when loading the ffmpeg plugin

[Athira]

When i got the latest version this issue was not observed.

But the new terminal in which the video is displayed is continuously switching between two dimensions. Thus giving the effect of alternating small and big frames of the video.

[Jean Le Feuvre]

could you post the sample file and OS version you use ?

[Athira]

The problem of Cannot find decoder for stream type MPEG-4 AVC|H264 Video still exists.

So I commented out the line :

gm_ffmpeg_in.so=Invalid Plugin

And then MP4Client was relaunched. It printed the following errors:

[h264 @ 0x2140180] no frame!
[h264 @ 0x2140180] no frame!

we will need the sample file to check your problem

I cannot reproduce your ffmpeg issue with a fresh install of 12.04.3 64bits with standard packages. Quite strangely, I can reproduce the resize bug using Unity with GL acceleration, but cannot reproduce it using unity2D or any gnome shell config ... I'll investigate
