gst/debug/: Add code for a pushfilesrc element that implements a pushfile:// URI handler, to make debugging push-mode...
Original commit message from CVS: * gst/debug/Makefile.am: * gst/debug/gstdebug.c: (plugin_init): * gst/debug/gstpushfilesrc.c: * gst/debug/gstpushfilesrc.h: Add code for a pushfilesrc element that implements a pushfile:// URI handler, to make debugging push-mode operation of demuxer/decoders that support both easier in connection with seek/playbin/etc. The element isn't registered at the moment.

* This element is only useful for debugging purposes. It implements an URI

* protocol handler for the 'pushfile' protocol and behaves like a file source
|

* element that cannot be activated in pull-mode. This makes it very easy to
|
||||
* debug demuxers or decoders that can operate both pull and push-based in
|
||||
* connection with the playbin element (which creates a source based on the
|
||||
* URI passed).
