There are various flavors of AVCHD, and I expect to see differing number of slices per frame, but this is not yet something I have investigated even though I have samples from a few different cameras. > decoding really multi-threaded? Maybe. For me, by default, it always complains "Cannot parallelize deblocking type 1," meaning no. However, if I supply the ffplay option "-skiploop 48" then the complaint goes away. I am still doing testing and investigation. > When using ffplay, I see only one core > working at 100%. How to activate multi-threading decoding. configure with --enable-pthreads and run ffplay with the -threads option followed by the number of worker threads to use. It will still keep a decoder control thread and separate reader/output threads, all of which are fairly light, so it is a good idea to use (#cores - 1) for the worker threads. -- +-DRD-+ ------------------------------------------------------------------------------ SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
