[FFmpeg-devel] I would like implement single-slice multithreading ffh264 decoding

[Rafał]

Hello,
I would like implement single-slice ffh264 decoding, but i don't know, 
what function has lots of % CPU, and result is not based on previous call

for example - decode_frame(...) - result is based on previous frame

please give me more information, about how to implement single-slice 
multithreading ffh264 decoding

sorry for bad english

Thank You,
R.M.
