pkg-config issue

[flenoir]

Hi,

when i try to clone and start the repository using "go get github.com/snickers/snickers"

i get a pkg-config issue telling me that all the packages from ffmpeg are not found ( libavutil, libavformat, etc....)

what should be done to solve this issue ?

Thank you

Best regards

hey @flenoir I'm afraid you don't have ffmpeg installed with --enable-shared config. Can you follow the steps on https://github.com/snickers/snickers#setting-up or just take a look at the dockerfile?

Hi Flavio,

Thank you for your reply.
So i recomplied ffmpeg with enable-shared.

the ffmpeg command returns now :

i ran "make build" but i now have another error in the compilation :

../../3d0c/gmf/codecCtx.go:220: cannot use unsafe.Pointer(this.avCodecCtx) (type unsafe.Pointer) as type *C.struct_AVCodecContext in argument to _Cfunc_call_av_freep

hmm @flenoir I'll try to reproduce it here. The FFmpeg I have is this:

ffmpeg version N-81113-g71167f7 Copyright (c) 2000-2016 the FFmpeg developers

It seems that it is older so maybe gmf is outdated with your version. I will get back to you soon.

@flenoir I installed FFmpeg from HEAD today and had no issues. Do you mind following the dockerfile steps?
