Dynamic encoder bitrate

[yileku]

I am new to gstreamer but I have question.  Is it possible to set the encoder to generate whatever bitrate is needed, in order to maintain the picture at the decoder?  So that the bitrate would escalate when the picture is changing rapidly, but then the bitrate would decrease if the picture was more static?


Thanks,

Yes. You can encode , either for constant quality  or for constant bitrate. In your case you are looking to maintain constant quality of encoded video , and you would not worry about swings in bitrate as encoder looks to keep up with details of rapidly changing scenes (by varying the bitrate).

Please take a look at last pipeline in this link for an example of encoding for constant quality using x264 encoder.  You can do same with x265 encoder as well.
