Building FFmpeg for Android

Question

I've spent almost a week on this now, trying to get FFmpeg "Angel"/"Happiness" to build for Android. I've tried build scripts from all over the internet to no avail. I got closest was using this. As the author himself says the script doesn't work for newer versions of FFmpeg due to this bug, which has been dismissed on that ticket saying "I found a Makefile that does it." This was dis-heartening, being the only post on all of the vast Google world that was anywhere close to my problem. So, question time:

Is there a way to get around the above bug? I'm trying to use the newest ffmpeg API, and "Love" is just giving me "undefined reference" errors while trying to use av_encode_video2(), and av_free_frame(). The code I was working on the lines of is at the ffmpeg git repo, under /doc/examples/decoding_encoding.c (the function starting on line 338).

Update: So they've done away with codec_names.sh in "Angel". Sorry didn't notice that before, but the problem persists in a different avatar now. With every build attempt the compiler throws a certain

start ndk-building...
/home/<user>/android-ndk/build/core/build-binary.mk:41: *** target file `clean' has both : and :: entries.  Stop.

Say whatnow!?

Answer 1

Given the lack of any response at all, I'm assuming people who know their shit in this topic are really busy putting their skills to use with whatever they managed to compile. For the ones like me who scraped each corner of the web for an answer that makes any little sense, I have a.. more than decent workaround.

The Guardian Project, an awesome resource on github, has the perfect project set up for building an ffmpeg binary with all the settings of your choice. But just the one big problem of getting it to successfully build sans the "Unable to create executables" error.

So.. there's a way out there too. Less flexible, but it saves you from losing any more hair than I'm sure you (like me) already have. Head out here and profit. From running the file command I noticed this binary was dynamically linked, that seemed weird, but it works.

Also, you'll have to run the chmod command before using it on the device (being a binary file and all). So pop it into your res/raw/ folder, load it up when needed and edit those videos like there's no tomorrow!
