<div dir="ltr">Hi, all<br> If some hardware vendors, such as TI provides only a sink OMX element (for example, mp3 sink), does GstOpenMAX have any plan to support it?

The idea is to map whatever OpenMAX IL is doing into GStreamer.<br> It should be fairly easy to create a new mp3sink element if that's<br> what OpenMAX IL is providing.
