[Mp4-tech] [video] HD in H.264/AVC FRExt with JM-9.0

[Gary Sullivan]

I would suggest either:
1) writing a little program that converts your input video to 1088 lines by repeating the bottom lines of each picture, and then feeding that to the JM as input video.
or
2) modifying the JM code to allow reading of non-multiple-of-16 sizes and do the padding when you read each frame into an array that is a multiple of 16 in size.
I would also caution you about doing complexity analysis using JM code.  It was not meant for that purpose, and was written in a way that may give you crazy over-estimates of complexity.
Best Regards,
