I did some debugging and that exception from CodecUtils.java:283 is coming from an IllegalArgumentException from the native code, but there's not much info to go on.

I have tried a variation of including / not including these keys on createVideoFormat:

KEY_PROFILE KEY_COLOR_FORMAT KEY_BIT_RATE KEY_DURATION

Replacing createVideoFormat with null works but I'm trying to downscale a video.

What's the best way to figure out what's going on?

Apologies for late response. Try adding KEY_FRAME_RATE to your video MediaFormat, some encoders don't like when it is missing.
