Hi Everyone, UC Berkeley and the UofS are planning to do some capture agent tests to see if we can finally move to x264 / mp4 as a possible default encoder / container instead of mpeg2. The current code base has some legacy issues where it assumed you needed to encode by quantizer but now you can encode by a constant bitrate or quality as the underlying gstreamer platform has moved on. There is also a host of properties (settings) that would be nice for users to be able to play with depending on the hardware they are using for their capture agents. Especially for the reference hardware there is a speed-preset setting that increases the performance a great deal. You can see the complete list here:
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-ugly-plugins/html/gst-plugins-ugly-plugins-x264enc.html (You can also run "gst-inspect x264enc" on your capture agent to find out what properties are available for a particular install version of gstreamer) I've created the review here and all comments are welcome: http://opencast.jira.com/source/cru/CR-MH-438 and it currently supports the properties: "interlaced" "noise-reduction" "pass" "profile" "qp-min" "qp-max" "quantizer" "speed-preset" If you think I have forgotten to add a property that you might need please comment on the review or reply here. If people would prefer I could refactor some of the capture agent code to allow any properties to be set on codecs & containers but this would decrease some of the spell checking of looking for particular properties on particular elements.
