Description

2016-12-28 20:33:43 UTC
Note to self: mpv-0.23.0 can dynamically load libcuda.so.1 at runtime to utilize CUDA-based video hardware acceleration. mpv still requires libavutil/hwcontext_cuda.h header, but this header is currently always installed by both ffmpeg and libav. Moreover, mpv does some tricks to avoid implicitly including cuda.h when including libavutil/hwcontext_cuda.h [1,2]. These tricks do work with current ffmpeg-git [3,4]. These tricks don't work with ffmpeg-3.2.2 [5], libav-12 [6], and current libav-git [7]. Thus, mpv currently requires both cuda.h and libcuda.so.1 for CUDA acceleration, i.e. nvidia-drivers and nvidia-cuda-toolkit. This later can be reduced to just nvidia-drivers for ffmpeg systems.

mpv-9999.ebuild
Please test the attached ebuild with 'cuda' USE enabled.
CUDA acceleration should work for you with it.
Hi, Tested the above mpv-999.ebuild (renamed it to 'mpv-0.23.0-r999.ebuild') in my local overlay, with GPU GTX 660, x86_64 kernel 4.4.39 and nvidia-drivers-375.26(~amd64) With 'cuda' flag enabled, the ebuild successfully pulls in nvidia-cuda-toolkit-8.0.44(~amd64). But mpv compilation fails with: ---------------------------------------------- Checking for CUDA hwaccel : no You manually enabled the feature 'cuda-hwaccel', but the autodetection check failed. * ERROR: media-video/mpv-0.23.0-r999::Local_Overlay failed (configure phase): * configure failed ---------------------------------------------- Not sure what exactly is wrong... 'emerge --info' and 'build.log' are attached. Regards, Alex Created attachment 458026 [details]

Build log
UPD. Tried to build mpv from git, both master and 0.23.0 branch. Both end up with same 'autodetection check failed'. waf configuration log is attached. Maybe it might help. Created attachment 458030 [details]
Configuration log for git version
(In reply to Alex from comment #3) Thank you for testing and comprehensive info. Please save the following code to a file, e.g. test.c: #define CUDA_VERSION 7050 typedef void * CUcontext; #include <libavutil/hwcontext.h> #include <libavutil/hwcontext_cuda.h> int main(int argc, char *argv[]) { enum AVHWDeviceType type = AV_HWDEVICE_TYPE_CUDA; AVCUDADeviceContextInternal *foo; return 0; } and compile it with gcc like this `gcc test.c'. If there are any errors, please post them here. With nvidia-cuda-toolkit-8.0.44 and gcc-4.9.4 the above code snippet says the following:
----------------------------------------------
alex@genty:/tmp$ gcc test.c
In file included from test.c:6:0:
/usr/include/libavutil/hwcontext_cuda.h:23:18: fatal error: cuda.h: No such file or directory
#include <cuda.h>
^
compilation terminated.
-----------------------------------------------
UPD. Afaik, the problem is in 'hwcontext_cuda.h' In my '/usr/include/libavutil/hwcontext_cuda.h ' it says: ------------------------------------------ #ifndef AVUTIL_HWCONTEXT_CUDA_H #define AVUTIL_HWCONTEXT_CUDA_H #include <cuda.h> #include "pixfmt.h" ------------------------------------------ In ffmpeg's current git master it says: ------------------------------------------ #ifndef AVUTIL_HWCONTEXT_CUDA_H #define AVUTIL_HWCONTEXT_CUDA_H #ifndef CUDA_VERSION #include <cuda.h> #endif #include "pixfmt.h" ------------------------------------------ After copying 'hwcontext_cuda.h' from ffmeg's git, and adjusting the code snippet to use it -- the snippet compiles successfully. But this way requires too much fixing by hand, and is hardly usable practically... (In reply to Alex from comment #10) > Afaik, the problem is in 'hwcontext_cuda.h' The problem is nvidia-cuda-toolkit doesn't set C_INCLUDE_PATH, see bug 604178. Don't worry, I can probably workaround it. Great! Thanks! Created attachment 458052 [details]
mpv-9999.ebuild
Please try this updated ebuild instead.
(In reply to Coacher from comment #13) > mpv-9999.ebuild > Please try this updated ebuild instead. This one (renamed it to mpv-0.23.0-r9999.ebuild) also ends up with "autodetection check failed"... Build log is attached. Created attachment 458054 [details]
Build.log for mpv-9999.ebuild

WAF configuration log
Ok, we finally reached the end. mpv needs AVCUDADeviceContextInternal type, which is only available in ffmpeg-git [1,2]. Thank you very much for testing. Sorry, but you'll have to wait for the next major ffmpeg release. As soon as it arrives I'll add CUDA support to mpv ebuild.

If any tests will be needed, put a message here -- I will receive it by email and will make them out. Thanks a lot for your time! Regards, Alex BTW, Happy New Year, to all! (In reply to Alex from comment #26) > If any tests will be needed, put a message here -- I will receive it by > email and will make them out. I just thought that if you don't mind trying ffmpeg-9999 then I can attach another ebuild that hopefully will provide you with a working CUDA HW accel. But ffmpeg-9999 will most likely trigger a rebuild of several more packages. (In reply to Coacher from comment #28) > I just thought that if you don't mind trying ffmpeg-9999 then I can attach > another ebuild that hopefully will provide you with a working CUDA HW accel. Sure I will test it asap. Created attachment 459810 [details]
mpv-9999.ebuild
Here's an updated ebuild. You need to install ffmpeg-9999 for it. Please make sure that dev-util/nvidia-cuda-toolkit is NOT installed prior to merging this ebuild. Hopefully CUDA finally works with it.

I unmerged nvidia-cuda-toolkit, installed upstream's ffmpeg-9999, and then emerged mpv with the new ebuild. It neither pulled anything else nor printed any errors on build.

It seems so. I've already subscribed to that issue. Thank you very much for taking this upstream. PR: https://github.com/gentoo/gentoo/pull/3503 This PR adds cuda support only to 9999.
