Hey guys, is there any reason why you have forgotten about this? A working 
transcoder is absolutely necessary, not only for posterity but for 
intermediate use where data loss is not desired. I have uploaded another 
sample (not sure who has it already) which, when encoded as UtVideo and 
decoded by ffmpeg, will cause an error.

Trac issue is here:

Please somebody examine the patch, confirm that it works, and merge.

Thanks.
