[x264-devel] Encoding a single input files to multiple output files with different bitrates

[Kiran Kotla]

Hello,

I am trying to use x.264 to generate multiple output files with different
bitrate from a single input file.

I want to do this in the most efficient way possible. Does x.264 already
provide a way to do this?

As in, after a common motion estimation step, is it possible to generate
multiple output files (with different bitrates), rather than having to go
through most estimation phase for each output bitrate?

If, this functionality is not available, any pointers to where to make
changes, would be appreciated.

I am looking at the function x264_macroblock_analyse and trying to use
multiple 'qp's each for one output bitrate, but the changes look quite
complex.

Appreciate any suggestions.

Thanks in advance
Kiran
