Question about integrating proprietary h264 encoders in gstreamer

[Carlos Rafael Giani]

Note that I am working on getting rid of the VPU wrapper for various 
reasons. Other than that, I agree.

I would recommend to try and write a GStreamer encoder element, based on 
the GstVideoEncoder class. This is generally simpler and less 
complicated than the FIFO approach, especially for real-time encoding. 
If this really is not possible for whatever reason, then a FIFO could 
work. Be sure to use the h264parse element to group input data into 
frames. Example: gst-launch-1.0 filesrc location=/tmp/my-fifo ! 
h264parse ! matroskamux ! filesink location=encoded-video.mkv
