Is it possible to build ffmpeg with SSL support on Windows Subsystem for Linux (WSL)

[asElhadidy]

Is it possible to build ffmpeg with SSL support (--enable-openssl) on WSL?

I have tried to install openssl using these commands

sudo apt-get install openssl sudo apt-get install libssl-dev

Modified configure to include --enable-openssl option, but it always gives the error "Error: openssl not found"

Is it possible or I need to build openssl on windows system?

Hi @asElhadidy,

Funny you should ask. I just did this last night. I'm gathering the steps and will be posting documentation about how to do this.

Unfortunately, getting the Linux openssl implementation doesn't work, you need a windows version of openssl. You can start with our fork for UWP at https://github.com/microsoft/openssl to get the openssl binaries.

I'll gather up the proper patches and push them on a branch shortly.

Hi khouzam,

Great, this will be a very good addition to your excellent work on WSL. I'll try to compile openssl on windows as your suggestion. Hopefully, I can get it to work. If not will definitely wait for your patches :)

I'm not an expert on Linux systems but I thought it is possible to cross compile the full ffmpeg stack (and its external libraries) on Linux, is this technically possible or I have misunderstood something?

Does the current build of ffmpeg interop include ssl support?

[asElhadidy]

Hi ryanwinter ,

No it doesn't include ssl support. Hopefully it will be added shortly.

I've added a preliminary support for building FFmpeg with OpenSSL through vcpkg a new Microsoft C++ package manager. This is still experimental, but seems to work really well. Please see my last post for issue #136 which talks about it.

If you checkout branch ffmpeg-openssl instead of ffmpeg-uwp, then openssl support will be included in the build of FFmpeg and you'll be able to playback streams over https.

Please try it out and provide feedback.

Hey @khouzam ,

What you wrote in #136 for vcpkg works well for me with ffmpeg-uwp but when doing the build for ffmpeg-openssl I get an error:

fatal error C1107: could not find assembly 'windows.foundation.foundationcontract.winmd': please specify the assembly search path using /AI or by setting the LIBPATH environment variable

This was on a machine with VS 2015 & Windows 10 SDK 10.0.14393.0.

Any chance you know why it's unable to find the file?

Here's my log files: make-openssl-x86-uwp-err.log.txt make-openssl-x86-uwp-out.log.txt

Thanks, Bill

Hi @bvenhaus .

Can you show the contents of the C:\Program Files (x86)\Windows Kits\10\References\Windows.Foundation.UniversalApiContract folder?

We might have missed a reference version.

[billvenhaus]

Sure. It's got just the one "3.0.0.0" folder

Hi @khouzam ,

Is there any chance you can upload or send me the compiled packages from your "ffmpeg-openssl" branch? Today, I installed a fresh copy of Windows 10 with VS 2015 & I'm still seeing the same issue. I am however able to build OpenSSL independently. I'd really like to integrate this into my Home Remote app.

Thanks, Bill

@bvenhaus I've pushed a branch (ffmpeg-openssl-contract-fix) to the main vcpkg repo that should fix this issue. If it does, @khouzam can pull it back into his branch.

Would you mind trying this out?

git checkout -b ffmpeg-openssl-contract-fix ffmpeg-openssl
git pull https://github.com/Microsoft/vcpkg ffmpeg-openssl-contract-fix

[khouzam]

Thanks @ras0219-msft, I've updated the ffmpeg-openssl branch.

@bvenhaus, can you try it now? I'll build a nuget package but that this will not be an official Microsoft endorsed one.

[billvenhaus]

Thanks guys, still getting the same error though.

@ras0219-msft here's the logs from your branch.

make-openssl-x86-uwp-err.log.txt make-openssl-x86-uwp-out.log.txt

@khouzam here's the logs from your updated branch

make-openssl-x86-uwp-err.log.txt make-openssl-x86-uwp-out.log.txt

Thanks @khouzam That'd be great! I don't mind if it's not an official Microsoft package.

[khouzam]

Ok, here's my personal nuget package link: FFmpeg-OpenSSL nuget.

It contains both the Desktop and UWP versions for x86, x64 and ARM.

With a project open, go to Tools->NuGet Package Manager->Package Manager Console and paste: Install-Package vcpkg-export-20170630-133459 -Source "<download path>"

[billvenhaus]

Thanks!
