Hi Phyllis, Andrew My script was just a proof of concept, can cinelerra use external tools for proxy file creation or not. The answer is Yes.
how does Cinelerra work with this proxy file and switch back and forth to the "real" file As I remember, the user must create a proxy file with external script, and the next step is to tell cinelerra to use proxy. It won't recreate proxy files because they already exist.

I think there is an easy solution to the below, but I am not sure what it is?
After reading Andrea's email as referencing vaapi/proxy/ffmpeg speed up from the original thread as Andrew pointed out below, I see a problem that I do not understand how to make workable. I was starting to make an update to the manual about having vaapi_proxy.sh in the doc directory for user usage when I got confused.

I added vaapi proxying script to our doc/ directory (really not fan of retyping scripts from manual ...)
Andrea Paz's reply below:
I made a build with the 2 patches of "configure.ac" + the other 4 patches ("cleanups"). I have no errors. I have not tried the proxy.
Problem: Andrey Spitsyn vaapi speedup using ffmpeg at 30x faster is a HUGE gain, but I do not see how it can be integrated into CinGG as in his suggestion of "So I thought that cinelerra can use this script to speed up the proxy files creation." 1) of course, it would only work if user had graphics board with vaapi capable acceleration but there are users who do; 2) but the real problem is if you run this script outside of CinGG, then how does Cinelerra work with this proxy file and switch back and forth to the "real" file and in the end have the changes applicable to the real file when you edit/render it in the future?
Hoping Andrea Paz pursues testing a way if someone has a hint of how to do this? Or am I just missing something?
