Subject: ringbuffer: Add support for E-AC3
X-Git-Tag: RELEASE-0.10.36~759
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9615081f9c3a04f83b3e3bee1dcdf90b08978da8;p=platform%2Fupstream%2Fgst-plugins-base.git

ringbuffer: Add support for E-AC3

Adds support for pushing E-AC3 buffers and doing bytes-to-ms conversion
correctly. The assumption (as with other formats) is that something like
IEC 61937 payloading will be used. Correspondingly the ringbuffer spec
is populated so that the data rate is 4x normal AC3.
