<br>
I am trying to write a pipeline which generates thumbnails of
video files using pngenc.<br>
<br>
My pipeline runs without any error but the output png image is of
0 bytes size i.e. nothing was written onto it.<br>
<br>
Below given is my pipeline:<br>
<br>
filesrc location=video.avi ! decodebin ! ffmpegcolorspace ! pngenc
! filesink location=video_thumb.png<br>

this won't work. You are trying to produce one ng for every frame
and send them to the same file. Take a look at the snapshot feature
in playbin2/camerabin2.<br>
