As part of our development work on Android, we were forced to
cross-compile GStreamer 1.12.4 with clang for Android ARM v7a We now have a set of bash scripts which accomplish this task, in case anyone else is interested. There are several caveats: 1) We've only tested the build scripts on Linux, specifically the OpenSuse and Centos distros, as that's the environments we work in. We don't support either Mac or Windows builds. 2) We don't build everything. In particular, we only ported the minimal set of libraries needed to support all of the elements that we use, but the framework is now in place for adding more libraries. 3) We've only tested cross compiling to ARM7, although it should be relatively easy to change the target. 4) We have custom patches in place to support the conversion. Some fix issues in the libraries, but others are unoffical bug fixes or new features for some of the elements we rely on. You will probably want to strip them out. 5) We only compile down to the individual libraries. Pulling them altogether and linking them with gstreamer_android.c is something we left up to Android Studio, for maximum flexibility, but we can supply our Android.mk file for building the final library. I don't know if these scripts will be of use to anyone else, but it took a few months of development and testing to get them working, so we're willing to release them, with minimal documentation or handholding. So, this is far from a final solution, but if someone needs a quick-and-dirty clang conversion for gstreamer, here it is. -- Stirling Westrup Programmer, Entrepreneur. https://www.linkedin.com/e/fpf/77228 http://www.linkedin.com/in/swestrup http://technaut.livejournal.com http://sourceforge.net/users/stirlingwestrup _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

There isn't a public link yet. I was trying to judge if there was
enough interest that I should clean up what I have, create a new github instance, and upload it.

There is, there's even a bug about that already: https://bugzilla.gnome.org/show_bug.cgi?id=759737 Can you link your results there too when you publish them?

Sorry for the long delay, but I was on vacation. I'm back now, and as
there is interest, I'll work on putting stuff up on github. I'll let you all know when its done.

Okay, I've finally gotten the time needed to finish the cleanup and
upload our work to github.

Stirling, nice job! I checked out the LICENSE file in your repo and it looks like GPL which I think is not the gstreamer license. You probably meant to go with LGPL. If you go with GPL, then it creates a barrier that prevents many people from using your work (and perhaps collaborating on it). LGPL removes that barrier.

I have a CMake file that does this. I think a better solution than bash script files. It's used for building the Alexa Client sample app for Android. If there is enough interest I'll check it in to my GitHub account. Joel Winarske On Thu, Jul 5, 2018, 4:03 AM David Ing <[hidden email]> wrote:

The license file is a copy of the COPYING file from GStreamer itself.
The intent was to use the same license, but you're right, as a derivative work, it may want a more relaxed license.

I already have an Alexa stack using CMake in which GStreamer is a dependency. It's a matter of using the Android toolchain file, and passing the proper variables. The build depency can be a universal GStreamer build, or specific machine architecture. I'll take a look at what you have over the weekend.

Joel & Stirling, I wanted to let you know that I am interested in any work as it relates to Clang + Gstreamer. I am also interested in Joel's cmake solution. I sincerely appreciate any public repos that you can create to document your efforts. I will be looking at Gstreamer + Clang in about 9 months from now (I'm not there yet). I am likely to use a cmake solution if Joel's is available, otherwise I will probably try to pythonize Stirling's shell scripts. Thanks for all your efforts thus far.
