Supporting -profile:v

[davodm]

Hi, I just added these flags to video options and I can't generate the video cause it gives me this error:

Error: Error: ffmpeg exited with code 1: Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

And my flags are (to be supported in whatsapp):
.flags(['-profile:v baseline','-preset ultrafast','-movflags +faststart','-level 3.0'])

Is there any solution to fix this problem?

I fixed it with this trick:
1- unset pixelFormat attribute from videoOptions
2- set flags like this:
.flags(['-pix_fmt', 'yuv420p','-profile:v baseline','-preset ultrafast','-movflags +faststart','-level 3.0'])
