[Libav-user] how to modify parameters during the encoding

[Jan Pohanka]

Hello,
I wonder if it is possible to change encoding parameters such as
bit_rate, flag_qscale, q_min/max etc. during the encoding. I need it
because I have varying parameters of transmission channel. These
parameters are normally set up at the beginning and initialized by
calling avcodec_open() function, I think that recalling it is not a
good way because it initializes some memory.

Is there please any way how to modify mentioned parameters like I need, please?

regards
Jan
