Description

Summary of the bug:

With a homegrown cross-compile of ffmpeg - OpenCL used to work, now it doesn't.

I last successfully cross-compiled ffmpeg with OpenCL to run under Windows, using a variation of rdp's build script on 2017.11.02.
In that build, OpenCL worked, i.e. the "-opencl_bench" option was recognised.

Now, using the same build process on 2017.11.25, the "-opencl_bench" option is no longer recognised.

Is it a bug, or has something changed that I need to cater for in the cross-compile process ?

How to reproduce:

see build switches above
cross-compiled under ubuntu17.10/mingw64 for the static target .exe to run under windows 10.
built on 2017.11.25

oops, the first config log attached is for 32bit, please ignore it.
the 64bit config log will be added shortly.
a dummy's question: is there a build log ?

OK, rebuilt ffmpeg all with the same cross-compile build process, using the commits just before and just after the recent OpenCL changes and sure enough ... -opencl_bench works with the .exe built before but not using the .exe built after :(

Suggestions welcomed.

old OpenCL version that works -opencl_bench

comment:3 Changed 3 weeks ago by hydra3333

  • Summary changed from problem cross-compiling ffmpeg with OpenCL to newly broken build process - cross-compiling ffmpeg with OpenCL

comment:4 follow-up: Changed 3 weeks ago by heleppkes

The experimental -opencl_bench option has been removed, and a bunch of the OpenCL video filters have been re-implemented using a newer more stable architecture.

comment:5 Changed 3 weeks ago by cehoyos

  • Component changed from build system to undetermined
  • Keywords opencl regression added; build OpenCL cross-compile removed
  • Priority changed from normal to important
  • Resolution set to wontfix
  • Status changed from new to closed

This change will most likely no be reverted.

Replying to heleppkes:

The experimental -opencl_bench option has been removed

OK thank you. How does one now find out the numbers for "platform_idx=1:device_idx=0"

-opencl_options platform_idx=1:device_idx=0 -init_hw_device opencl -filter_hw_device opencl

Or has that been superseded by something else now ? (If so, what replaces it ?)

comment:7 Changed 3 weeks ago by heleppkes

All old experimental opencl options have been replaced by a new implementation. Maybe Mark can weigh in with an example of how to use it.

comment:8 Changed 3 weeks ago by hydra3333

Thank you. Great !

Besides "How does one now find out the numbers for "platform_idx=1:device_idx=0""

I must have done something wrong with this bit as well
-opencl_options platform_idx=1:device_idx=0 -init_hw_device opencl -filter_hw_device opencl
... refer below ... and so advice would be most welcomed.

The old -opencl_bench told me I have these devices - OpenCL using the nvidia 750Ti is the one I wish to use.
