So what happened is that the library in Debian providing support for live555 was removed in February of this year, this affects all downstream distros including but not limited to RPi OS and Ubuntu:

https://askubuntu.com/a/1363113

The 2 active versions were 2020.01.19-1 and 2018.11.26-1.1, Live555 has since added GPL license headers to the offending files, however the RFC issue remains.

Now you may be tempted to just download the latest Live555 source code and compile it... it does not work. There have been changes to function names and structures referenced by VLC, and as such VLC will not compile against the source. You need to get an older version, I specifically used this one, which is a tweaked snapshot from 2020 prior to the modifications that prevent VLC compilation:

https://github.com/rgaufman/live555

The configuration you want is ./genMakefiles linux-with-shared-libraries, I do not know if it is required but since my system is x86-64-bit I added -m64 to the compiler options first

After compilation and install, I went on to compile VLC, adding '--enable-live555' and '--with-live555-tree=extras/live555-master' after placing the root Live555 folder in the VLC extras folder, however VLC failed to compile, it turns out the Live555's make install does not copy all the header files needed to where VLC is looking. They were dropped as 4 subfolders into /usr/local/include/, and the actual libs into /usr/local/lib/. Adding the correct CXX/CPP flags will make it look where they were put, however I put them all in a single folder and used 1 flag.

I also had to '--disable-mod' to work around a dependency version issue that I had no interest in fixing, since I do not use modplug or any mod files.

50 minutes later... VLC successfully compiled! However it was expecting the libraries for Live555 to be in /usr/lib/ not /usr/local/lib/, since it took so long to compile I was just fine with linking or copying the libraries into the expected folder, and after that VLC works with RTSP when linked to the new file. Or you can choose to maintain the original VLC and run the new file directly if you need to load the camera feeds.

If you haven't solved this already, your error is nothing to do with opencv - it's cmake:

Building wheel for cmake (PEP 517): finished with status 'error'

which is required to install opencv.

You may find this thread helpful: ERROR: Could not build wheels for opencv-python which use PEP 517 and cannot be installed directly - there's an answer in that list that contains a Dockerfile which may work for you.

Ok, so I figured out what was the issue.

Even though I had the right FFmpeg configurations installed on my system (the one with --enable-hwaccel=h264_vaapi), the issue was that I was linking my program with the wrong version of libav, the one contained in libwebrtc, not the one from my system.

How to get FFProbe to run using dotnet core as an Azure Function in Docker?

Asked 2020-Aug-29 at 21:52

I am trying to get video details (length, height, width, and content type) from a video based on a URL. By using the nuget package https://www.nuget.org/packages/NReco.VideoInfo.LT I was able to create an Azure Function running locally pointing to my local install of FFProbe rather easily. However, the trick is now making it compatible with an Azure Function and, to the best of my knowledge, the easiest way to do that is by providing a Docker image that contains everything needed (this would be running on a Linux machine).

So, let's get into the code. Previously, this is what I had working if I ran the function locally:

Since you are new to Docker. Here I will show you something I have known.

You Dockerfile is to create an image with multiple stages:

With multi-stage builds, you use multiple FROM statements in your Dockerfile. Each FROM instruction can use a different base, and each of them begins a new stage of the build. You can selectively copy artifacts from one stage to another, leaving behind everything you don’t want in the final image.

From the description, you need to know all the FROM except the last one is the build pattern, only the complete the application will be copied to the last base image and run in it. So it is not the overwrite, it's a new running environment. You need to install all the dependencies for your application in the last base image if it does not already have.
