playback file is invalid

[GeekAnnoyed]

while testing on my debian wheezy system , I build and capture with no apparent errors but when I play back the video I get the following

xpd259@mars:/workspace/glc$ glc-capture -s -v 4 glxgears
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
