building on Ubuntu 12.04 about pyav HOT 4 CLOSED

@mkassner I am also using PyAV on 12.04LTS. I had to build FFmpeg from source. Since I went through so many iterations on this (and since my setup was customized/compromised before PyAV entered the picture) I can't offer up a definitive recipe. But I can offer an existence proof: it is possible to get PyAV working on 12.04. I will post some details about my setup (i.e., specific versions) later this week. Feel free to ping me if I don't return to this by Friday.

@danielballan The shell script I posted will install ffmpeg on a fresh 12.04 such that pyav does build. The questions that remains is wether pyav can be build with APT ffmpeg instead.

In it's current state, you will not be able to build PyAV on Ubuntu 12.04 using only default packages because the libav contained there does not (and very likely never will) include libswresample or libavresample.

I think this is another of the casualties of the political BS that created the ffmpeg/libav fork in the first place.

Unfortunately, I believe we use the audio resampling to make the encoding process more sane, and so we can't even just not build the AudioFifo and AudioResampler classes.

Seems like this is something to put into a more complete installation document, along with #30.

OK.It good to have definitive answer. I hope my script can be of use for others.
