Just compiled Cin with just one switch:

 ./configure --with-single-use

it worked with some local hacks (/usr/X11R7 for X libs, disabling swscale integration in x264 snapshot)

I can load my profile to

/dev/shm/cinelerra/cinelerra-5.1$ ls bin/ffmpeg/video/
DNxHR_HQX.mov

and it show up correctly and let me render.

Does your build enable vdpau/vaapi? As far as I can see those options loaded in

search for 'cin_pix_fmt'

so for some reason it fails to find best format via avcodec_find_best_pix_fmt_of_list ?

Also, I tried with default RGBA-8 colormodel ..... may be it fails with YUV/RGBA-float?

no, seems to work too ....

You can try and add printf("doing X \n"); in this function and see that branch it takes :} and also print out exact value of  cin_fmt

printf("cin_fmt= %i \n", cin_fmt);

something like this ...
