HDMI video support in Gstreamer
Locked
 
|
Hi all: I can’t find HDMI
video support in Gstreamer. Could anyone here tell me why? Not feasible or just
lack of resource? If someone has done some
investigation, could you please give me some hints? Thanks in advance.

Hi
Thanks for your info. And what I want to do is to develop a sink element to send decoded data to HDMI. Is it possible?

There is a base class for sinks (GstBaseSink). This is used e.g. by xvimagesink or ximagesink. Its recommened to use that, as it implements most generic functionality needed for A/V sync. What you need to find out is what api is used to output to hdmi on linux (is is v4l2?).

Why would it be any different from output through DVI, or another digital output? X should know how to drive it, the only hard bit being the HDMI audio.

Thank you all. And my thinking is that if we treat HDMI as generic digital output such as DVI, all display will be sent to HDMI. What I want is that only video/audio data playback within Gstreamer framework will be output to HDMI interface. Any comments? Thanks in advanced.
