it is not related to code above. it seems a bug in v1.

not working with v1:

ffmpeg -loop 1 -r 25 -i /usr/local/src/NDI/NDI.Image.png -vf 
"format=pix_fmts=bgr0" -f libndi_newtek -y png_bgr0
ffmpeg -loop 1 -r 25 -i /usr/local/src/NDI/NDI.Image.png -vf 
"format=pix_fmts=bgra" -f libndi_newtek -y png_bgra
ffmpeg -f lavfi -i "testsrc=size=1920x1080:rate=25" -vf 
"format=pix_fmts=rgb0" -f libndi_newtek -y testsrc_rgb0
ffmpeg -f lavfi -i "testsrc=size=1920x1080:rate=25" -vf 
"format=pix_fmts=rgba" -f libndi_newtek -y testsrc_rgba
