[Libav-user] does filter graph support multi-thread

[qw]

Hi,

There are several filters in one filter graph. I expect that, each filter can run in single thread instead of whole filters running in single thread. Should I use other multimedia framework working with ffmpeg, such gstreamer and openmax?

Thanks!

B.R.
