Question

I know that it is possible to change some encoder parameters on fly, using x264_encoder_reconfig(). From this commit I can deduce that we can change ratecontrol parameters - but I was unable to find a clear list of parameters that may be changed.

Question: which parameters of x264 encoder can be changed on fly?

Was it helpful?

Solution

You can look for the list of reconfigurable options in the source code of libx264 x264_encoder_try_reconfig function
