[Live-devel] Error in MPEG4VideoStreamParser::parseVideoObjectPlane()

[Muhammad Bilal]

If I use MPEG4VideoStreamDiscreteFramer instead of MPEG4VideoStreamFramer
then the error is removed.
But if we connect it through VLC player or Quick Time then NO VIDEO. However
if we use OpenRTSP to receive stream then it works fine. Can any body
explain what is lacking?
