GStreamer | gstreamer (core) | Ver: HEAD CVS
Summary: Add specific error code for encrypred streams (e.g.
WMA/AAC DRM)
Product: GStreamer
Version: HEAD CVS
Platform: Other
OS/Version: Linux
Status: UNCONFIRMED
Severity: enhancement
Priority: Normal
Component: gstreamer (core)
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: internalerror at gmail.com
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME version: 2.21/2.22
GNOME milestone: Unspecified
There is no specific error code for encrypted streams, even though asfdemux and
qtdemux can detect such streams (it could be useful when e.g. deciding whether
to import streams into a user's music library in a media player, or to test
programmatically whether a file can be played before playing it (when e.g.
reading its metadata before playing it back).
Currently a stream-decode error is issued in such cases which can not be
differentiated from genuine stream errors such as bad data.
The attached patches (one for gst-core one for gst-plugins-good and one for
-ugly) add the needed functionality to -core (STREAM_ERROR_STREAM_ENCRYPTED
error) and make asfdemux and qtdemux use the functionality (supposedly real
streams can be encrypted too but searching the code i couldn't find where this
is being detected).
