This is an automated email from the git hooks/post-receive script.
vcheng pushed a commit to branch upstream
in repository gstreamer-vaapi.
commit 2e356b0f7efae33fb943ad11204020dcdbf1b04f
Author: XuGuangxin <guangxin.xu at intel.com>
Date: Wed Nov 20 16:21:32 2013 +0800
plugins: add mpeg2 encoder element.
Add GstVaapiEncodeMPEG2 element object. The actual plug-in element
is called "vaapiencode_mpeg2".
Valid properties:
- rate-control: rate control mode (default: cqp - constant QP)
- bitrate: desired bitrate in kbps (default: auto-calculated)
- key-period: maximal distance between two key frames (default: 30)
- max-bframes: number of B-frames between I and P (default: 2)
- quantizer: constant quantizer (default: 8)
