[FFmpeg-user] what's the threads mode when using ffmpeg to transcode

2014-11-06 Thread cmwu
hi, I am confused how ffmpeg allocate it's cpu resource when i am using ffmpeg to transcoding, for example: how much resource to decode, and how much to encode I have set the threads to 1 and do a experiment: ffmpeg2.1 -i /home/mps/chd/out.avi -acodec pcm_s16le -ar 44100 -ac 2 -vcodec
