Comment 2 for bug 924725

Hi Xavier,

Following your recommendations I upgraded my env and retried a few mpegts movies after cleaning ~/.gstreamer-0.10 folder
Some mpeg-ts movies are well played but some others are not played for the same reason.

Here is the output of gst-discoverer-0.10 on a failing movie (caps width and height not computed by the parsers) :
