The principle sounds interestingly. Although I'm used with simple pipes, 
I have never used fifo file (name pipes).
But a real case ("workshop") example could make it clearer for me.

1. Will it be applicable for pre-built CinGG installed from appimages, 
or  from packages (einander) where "cin" can be started in a terminal ?

2. And let CinGG utilize my "system" ffmpeg (from Packman) for qsv gpu 
hwaccel encoding?

    ffmpeg -hide_banner -encoders | grep qsv
      V..... av1_qsv              AV1 (Intel Quick Sync Video
    acceleration) (codec av1)
      V..... h264_qsv             H.264 / AVC / MPEG-4 AVC / MPEG-4 part
    10 (Intel Quick Sync Video acceleration) (codec h264)
      V..... hevc_qsv             HEVC (Intel Quick Sync Video
    acceleration) (codec hevc)
      V..... mjpeg_qsv            MJPEG (Intel Quick Sync Video
    acceleration) (codec mjpeg)
      V..... mpeg2_qsv            MPEG-2 video (Intel Quick Sync Video
    acceleration) (codec mpeg2video)
      V..... vp9_qsv              VP9 video (Intel Quick Sync Video
    acceleration) (codec vp9)


3. Suggestion to this pipe line setup and running av1_qsv encoding from 
CinGG Render .webm?
