Package: gstreamer0.10-plugins-base Version: 0.10.36-2 The upgrade from Wheezy to Jessie broke mp4 playback in native Firefox 38.4esr (binary downloaded from http://ftp.mozilla.org). If I rebuild Firefox from source using gstreamer 0.10 on Wheezy it doesn't work on Jessie, either. There is surely a regression here.
Building Firefox with gstreamer 1.0 on Jessie seems to work, but for verification I am bound to upstream's binary blobs. Its highly painful. Regards Harri
