[Spice-devel] Intra-frame compress for spice video channel

[Qiang]

Hi, Dear all

I want to improve Spice bandwidth utilization, with a reasonable cost of 
more CPU utilization.
Under my test the audio(with opus) work fine under low bandwidth.
As I know the spice didn't use the intra-frame to compress the video data.
Under my test all the display frame be compressed as quic_data. But even 
use the
quic compress, it take huge bandwidth to play my 480P movie.
So I wanted to implement the intra-frame to compress(As an compress 
option.) based x264.

There are seem two ways.
1) drawable_data -> stream -> use the x264 instead the M-JPEG compressed.
I am struggling why this data didn't pass through the video stream. But 
as a quic_data.
2) quic_data -> transfer the quic_data to a rgb data -> use the x264 to 
compress it.
But I am not sure how transfer the quic_data to x264 input_data? there 
is so limited doc about this.

Any idea about the intra-frame or the video compression please let me know.

PS: Anyone know the new contact way of Yonit Halperin

Thanks very much.
