Ffmpeg on Fulong

Introduction

OK... so I was looking for things to do with the Fulong, so I headed over to Freshmeat and found something that interested me, namely a program called Clive.

Building

Well, reading up on this thing a bit more, it turns out that one of the options for it is to push the files through ffmpeg and urlgrabber in order to reencode them. urlgrabber is just a python script, so no big deal there, but I needed ffmpeg.

It turns out that ffmpeg is only available via svn (i.e. Subversion), and of course the Fulong doesn't have THAT installed. So now I have to install Subversion. Welcome to dependency hell. Subversion in turn requires apr and apr-util, both of which are parts of the Apache Portable Runtime. So I go and grab those. apr compiles and installs without problem with a simple configure and make. apr-util required a bit more finesse on the configure line because it depended on apr:

apr and apr-util

./configure --with-apr=/home/src/apr-1.2.12

subversion

OK, so we have the dependencies of subversion down. Now to build subversion. Of course, a bit more finessing on the configure line is involved here:

./configure --with-apr=/home/src/apr-1.2.12 --with-apr-util=/home/src/apr-util-1.2.12

ffmpeg

Well, that built, so now I was able to grab the subversion version of ffmpeg:

svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg

No problems, and subversion worked like a charm! Now to actually compile ffmpeg. Something interesting to note in the configuration is the following:

ARCH                      unknown (generic)

Go figure. This is a Chinese MIPS processor. Too bad it couldn't figure out the MIPS part at least.

Unfortunately, it breaks when it gets to doing a framehook against imlib2. Go figure, seeing as the build for THAT software was a bit sketchy itself because of a slightly munged dependency:

In particular I love the bit about vhook being deprecated. Well, let's try configuring without vhook. I really don't care all that much about imlib2 anyway, so let's try without it.

./configure --disable-vhook

A simple make after this seemed to get right by the problem area, but I am not sure I trust the build at this point so I stop the build, do a make clean, and restart the build from the beginning to be sure that the new options take effect across the entire build instead of just in the second half.
