    Re: HOWTO: Install and use the latest FFmpeg and x264

    Hi FakeOutDoorsman,

    Apropos of my previous post I have written another guide in a 'linux basics' series that may or may not be of some use to readers of your guide:

    Linux Basics: A gentle introduction to accessing 'svn' repositories
    http://ubuntuforums.org/showthread.php?t=1167578

    The special relevance to your FFmpeg guide is that I have used the FFmpeg svn repository as an example throughout the guide. Not sure if this is any help as you have covered the most immediate svn needs already...

    All the best,

    Andrew
    You think that's air you're breathing now?

    Re: HOWTO: Install and use the latest FFmpeg and x264

    Hi All -

    Looking for some help. Everything went well until step4 - Install FFmpeg

    When performing make I get this error:
    /home/rob/ffmpeg/libavcodec/libavcodec.so: undefined reference to `faacDecDecode'
    /home/rob/ffmpeg/libavcodec/libavcodec.so: undefined reference to `faacDecInit2'
    /home/rob/ffmpeg/libavcodec/libavcodec.so: undefined reference to `faacDecClose'
    /home/rob/ffmpeg/libavcodec/libavcodec.so: undefined reference to `faacDecOpen'
    /home/rob/ffmpeg/libavcodec/libavcodec.so: undefined reference to `faacDecSetConfiguration'
    /home/rob/ffmpeg/libavcodec/libavcodec.so: undefined reference to `faacDecInit'
    /home/rob/ffmpeg/libavcodec/libavcodec.so: undefined reference to `faacDecGetCurrentConfiguration'
    /home/rob/ffmpeg/libavcodec/libavcodec.so: undefined reference to `faacDecGetErrorMessage'
    collect2: ld returned 1 exit status
    make: *** [ffmpeg_g] Error 1

    I have Jaunty and I'm not too sure what else you need to help - please let me know and I will post. Ultimate goal is to get Fuppes to transcode but gotta get ffmpeg working first.

    I just compiled FFmpeg revision SVN-r18971 on Jaunty and encountered no errors. There may have been issues with your particular revision. I recommend trying the newest revision. Go to the Updating Your Installation secion of the guide and start at cd ~/ffmpeg. Let me know if that does not work.

    Thanks for the response! The latest was revision 18972 and now I have this error:

    Do you need more information?

    Did you change anything from the guide? Give the output of:
    Code:
    tail ~/ffmpeg/config.err

    Re: HOWTO: Install and use the latest FFmpeg and x264

    I copy/paste. I have tried a number of tutorials before I got to this but fuppes would never transcode. I thought this tutorial may be the answer but now I cant play anything using Mplayer/ splayer/ vlc, etc.

    Here is the output:

    rob@Base:~/ffmpeg$ tail ~/ffmpeg/config.err

    I'm not sure what is causing your error and I can't duplicate it. I would guess it is a conflict with an installed package; possibly from a non-Ubuntu repository. Check /etc/apt/sources.list and /etc/apt/sources.list.d/ for any non-Ubuntu repositories.

    Perhaps the problem is caused by the prior tutorials you followed. Do you have links to those tutorials?

    If I can't figure this out the next step is asking for help in the #ffmpeg IRC channel or at the ffmpeg-user mailing list.

    Re: HOWTO: Install and use the latest FFmpeg and x264

    Thanks for the how to. Worked like a charm. How often do those packages get updated? Does svn trunk mean it is more of a stable than the beta packages? I have understood svn to be beta stuff, but that is more just my impression than factual.

    Glad it worked for you. Development is active for both FFmpeg and x264. Yesterday there were two updates to FFmpeg and Saturday had eight updates. You can see a FFmpeg changelog with:
    Code:
    svn log -l 6 svn://svn.mplayerhq.hu/ffmpeg/trunk
    The option -l 6 will display the last six log entries. You can view the x264 changelog in your browser. Your installed FFmpeg and x264 packages can be updated as often as you would like. Refer to the "Updating Your Installation" section of the guide.

    I'm not aware of any FFmpeg beta packages and since I've been using FFmpeg it was always recommended to use SVN. It is the bleeding-edge and I have experienced errors, but the are relatively rare and usually fixed by the next day. From ffmpeg.org/download.html:
    FFmpeg has always been a very experimental and developer-driven project. It is a key component in many multimedia projects and has new features added constantly. SVN snapshots work really well 99% of the time so people are not afraid to use them.
