I do not know if info above will be help to give me some other advice . I do not think any words can be helpful to show my appreciation for your help . </BLOCKQUOTE> The parser didn't fail, but simply reported a broken stream. As the pipeline I've given you worked, I can confirm you are currently streaming a ISOMP4 stream to an H264 parser. This is not the same format. ISOMP4 is a container format, while H264 is a encoded video stream. Here is some lecture to help you learn the difference between elementary packet and container package: Containers: <A HREF="http://en.wikipedia.org/wiki/Container_format_%28digital%29">http://en.wikipedia.org/wiki/Container_format_%28digital%29</A> <A HREF="http://en.wikipedia.org/wiki/QuickTime_File_Format">http://en.wikipedia.org/wiki/QuickTime_File_Format</A> Elementary Packet: <A HREF="http://en.wikipedia.org/wiki/Video_compression_format">http://en.wikipedia.org/wiki/Video_compression_format</A> <A HREF="http://en.wikipedia.org/wiki/H264">http://en.wikipedia.org/wiki/H264</A> cheers, Nicolas </BODY> </HTML>
