It could depending on the stream. I forgot to mention that you need 
multithreaded decoding.

H.264 is a complex format. The computing power needed for decoding 
varies with bitrate and used parameters.

It is H.264, at least all samples I have seen. Do you still have the 
filename of that sample? Is it still somewhere available? I'll look 
tomorrow which sample I've tested. Your error descroiption sound like 
the artifacts for spatial direct mode with interlaced frames. That 
might or might not be fixed in latest fmmpeg svn.
