I created a 1.2GB gdp payloaded 1280x1024 series of videotestsrc jpeg2000
encoded files. Then I muxed this into avi. The resulting file created an avi
superindex and was not playable on WMP. mencoder on the file made it work. Then
I started to look at the differences between the working and failing avi. After
experimenting with some fields and flags, it seems that WMP needs a valid
bufsize in the stream header.

Patch below calculates this buffer size correctly and makes the file play on
WMP. Please check if it also works for you, if not, reopen this bug.

    avimux: calculate suggested buffer size

    Calculate the suggested buffer size based on the largest chunk in the file.

    See #597847
