I proved to disable audio clossing the audio parts with a if( audio.st ) but finally the video part also fails.
For now, I use an avconv audio filter to add audio silence to nut stream.

@calanor @lu-zero Can you share a solution to a play video file without audio ?
from bmdtools.
Add silence to input source:
avconv -vsync 1 -f lavfi -i aevalsrc=0 -i <source> -c:v rawvideo -pix_fmt uyvy422 -c:a pcm_s16le -ar 48000 -f nut -f_strict experimental -syncpoints none - | ./bmdplay -f pipe:0

Hi calanor,
Thank you for your suggestion, when I execute is this is the error I get.
Unknown input format: 'lavfi'
Segmentation fault (core dumped)
from bmdtools.
It seems that libav don't have aevalsrc audio filter.
Use ffmpeg instead avconv.
Tested without errors with ffmpeg .
from bmdtools.
You do not need to use any filter to have a silent audio though.

@calanor Hey thank you very much it solved the problem.
@lu-zero When ever I play a video file without audio I get no audio found and bmdplay will stop. After @calanor solution I was able to solve that.

The common way to add an audio track is to just take /dev/zero
as audio input.
I agree that's sub-optimal.
