<p>Forget it. Posting this question made me pay more attention to the log: if anyone is interested the answer is that you have to specify the colour space - "-pix_fmt yuv420p" in my case. Sorry guys.</p>

What's the default profile and colour space that's used if you don't specify either `-profile:v` or `-pix_fmt` ?

<p>Ok, I have a feeling this might be a silly question, but I can't see what I am doing wrong. This is my command:</p>

<p>ffmpeg -i input.mov -c:v libx264 -profile:v baseline output.mp4</p>

<p>and the error it returns is: "Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height"</p>

<p>I tried specifying the audio codec and using the other profiles, all to no avail... But the command works if I drop the -profile</p>

Great question and I'm surprised ffmpeg doesn't use a default pixel format for the baseline profile like it does with the high444 profile.

# Error while trying to set ffmpeg profile

(Asked by: username_0 on 2016-12-23)

Ok, I have a feeling this might be a silly question, but I can't see what I am doing wrong. This is my command:
ffmpeg -i input.mov -c:v libx264 -profile:v baseline output.mp4
and the error it returns is: "Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height"
I tried specifying the audio codec and using the other profiles, all to no avail... But the command works if I drop the -profile
