You are mixing up what FFmpeg calls "FLV" - the
Flash file format - with what FFmpeg calls "flv1" -
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).
