Hello there!
I have modified mp4 file placed on HTTP server. File is playing via decodebin2. Now I added additional information (512 bytes) to beginning of file, this information has to be ignored by gstreamer pipeline. Is there possibility (f.e. some element or property) to skip first 512 bytes and work with tail of file regular way? For me its important to use seeking in push mode. Sincerely, Kyrylo V. Polezhaiev. _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Not really, as this won't be a valid mp4 file anymore. I'd suggest to put your extradata into a custom atom inside the mp4 instead. Then gstreamer will simply ignore the unknown atom.

Can I wrote some new element (skiper) instead? :-)
