[gst-devel] Smooth rewind with Gstreamer

[Julien Moutte]

Hi,

Are you sure your video decoder supports reverse playback scenario ?

It will receive frames in decoding order, it should queue them
internally and push them in reverse order when it receives an incoming
buffer with the DISCONT flag.

Please also make sure you have a big queue behind the video decoder so
that it can take some advance compared to the rendering element.
