If you get this error, you probably tried to infer against a model URL that doesn't exist.

We should surface this and not let the script try to compile the inference video without output frames

I encountered this issue - for anyone that might be having this in the future:

As stated above, the script is inferring against a URL that doesn't exist.

• First thing to change is the set the host to https://detect.roboflow.com (this seems to be the replacement to infer. You can change the default, or set --host)

• Then, Search for "access_token" and change this to say "api_key' instead, to reflect the new parameter name

I was getting the same error due to the detect.roboflow.com API returning slightly different error messages than those being checked in infer.sh, which I've fixed in PR #4.

Might be worth adding a sanity check to ensure the returned data is actually a JPEG on the first API call.
