> Hi,
> I was searching the FFMPEG documentation on enabling OpenCL & selecting/specifying an OpenCL device. Here is what I could find:
> 1) Enabling OpenCL while building OpenCL: https://trac.ffmpeg.org/wiki/HWAccelIntro
> 2) Specifying an OpenCL device to be used: <install_prefix>/share/doc/ffmpeg/ffmpeg-utils.html#OpenCL-Options

> I did not find much information on the auto-selection of an OpenCL
> device using the -opencl_bench. What is the best way to update this
> documentation to include information regarding the auto-selection
> logic from a user perspective?

> I would use assume it would be a patch that modifies the files used
> to generate ffmpeg.html and ffmpeg-utils.html (i.e. doc/ffmpeg.texi
> and doc/ffmpeg-utils.texi).

You have to edit doc/utils.texi. The file is automatically included in
all the other relevant texi files.
> Please let me know your thoughts on this before I proceed with
> working on a patch for this documentation.
