Minimum frame size for H.264 encode

Are there minimum dimensions that the encoder will take for width x height?

I've tried to set them to 320x192, but MFXVideoENCODE_Init bumps it up to 480x272.

I have definitely had 320x180 encoding working. Specifically, this 62 megabyte video found on this page: http://www.bigbuckbunny.org/index.php/download/ With the title: "IPod 5G 320×180, 62 MB" Maybe there are other factors or variables at play. You might try sample_decode/sample_encode on the Big Buck Bunny video to convince your self that is not a constraint. (I have gone through this process.) Please let us know what you find out.

Thanks for verifying that it is supported. When I read your post, I realized what was going on. I need to use a custom SPS/PPS. The SPS that I was using clashed with the input parameters. Now the custom SPS's match the encoding parameters and all is well.
