How to display Live streaming?

Jump to solution

Now I have finished the decoding thread and finished the debugging.

The following is a part of my project :

decoder chain like this:

UDP recv--->rtp unpack---> vcu dec, and then  get the AL_TBuffer *pDisplayedFrame which holds the yuv BUFFER.

you can see that the screenshot is 14000+ frames of decoder, can run stably .

All right, now I'm more concerned if there's an example of an upper-level application code for me, and I can add the Display functionality to it.

I need Display Example Code, like exe_decoder in vcu_ctrl_sw

best wishes!

Xilinx uses the Linux DRM KMS Framework, so you could look at code like modetest from libdrm.  You could also look at the video_cmd that is part of the HDMI Frame Buffer Example design.


You might also want to consider using a higher level API like GStreamer.
