You are mixing up what FFmpeg calls "FLV" - the 
Flash file format - with what FFmpeg calls "flv1" - 
Sorenson Spark.
This mailing list thread is about h264 and flv.
H264 does support multithreading, file formats do 
not support multithreading (neither flv nor any 
other format), but note that this does not matter 
because for every "real" codec (like H264), decoding 
takes a magnitude of resources more than demuxing, 
demuxing time never has impact on the time needed 
for the whole process.

FFmpeg's Spark encoder and decoder ("flv1") does not 
support multi-threading, but as said, it was not 
mentioned in this thread (before).
