Although the patch   0001-Fixup-seg-name-to-segment-so-format-gui-button-work.patch   works at our current version of ffmpeg 7.0 as does the audio render format "bluray_lpcm.seg" with the first line of "segment_format=mpegts", the corresponding video render format "mpeg2hd422p.seg" does not -- at least it fails for me.  Its error message is:

FFMPEG::encode_activate: write header failed /tmp/ccc.seg
  err: Muxer not found

I will see what I may have done wrong.

if it literally reads 

segment mpeg2video

segment_format=mpegts

segment_time=00:10 <= your segment time

reset_timestamps=1

cin_pix_fmt=yuv422p

then "your segment time" was comment not meant to put in there in this form, just reminder for human reader .... may be it choke on this?
