Link to original bug (#705703)

Description

The attached MP4 video stream does not play. It appears to get an invalid seek position upon start up (see attached log). It works fine when played as a local file. It fails when served from Apache WebServer using souphttpsrc.

To reproduce:
gst-launch-1.0 playbin uri=http://192.168.0.106:818/B-04.MP4

Version: 1.x
