GStreamer | gst-plugins-bad | Ver: 0.10.14
Summary: mpeg2enc deadlock
Product: GStreamer
Version: 0.10.14
Platform: Other
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins-bad
AssignedTo: gstreamer-bugs at lists.sourceforge.net
ReportedBy: s355248 at student.uq.edu.au
QAContact: gstreamer-bugs at lists.sourceforge.net
GNOME version: Unspecified
GNOME milestone: Unspecified
The following command produces a deadlock in the mpeg2enc plugin.
gst-launch filesrc location="file.mov" ! qtdemux name="demux" avimux
name="mux" ! filesink location="output.avi" { demux. ! queue ! ffdec_mpeg4 !
videorate ! mpeg2enc ! queue ! mux. } { demux. ! queue ! decodebin !
audioconvert ! audioresample ! ffenc_mp2 ! queue ! mux. }
The file I'm using (i.e file.mov) is actually
http://oodt.jpl.nasa.gov/better-web-app.mov. It is over 300mb.
