    I listed all modifications that i made in my post. Here is the modified script in it's entirety:
    https://docs.google.com/leaf?id=0B8_...iMWQ3&hl=en_US
    If you would like to add me as a member to your code.google project, i could upload it there.

    A user-friendly front end to your script could be to write it using zenity ;) Let me know if you would like some assistance making the modifications to have a zenity front end.

    Cool, I'll check your version out.

    You don't need to be a member of my project to post comments on google code, just use your google login.

    I did consider providing a zenity interface, but as the script makes some potentially big changes to your system, I wanted it to be a little daunting for those who know nothing of the command line, so they knew the seriousness of what they were doing. Giving sudo access to a script that they got off the internet is not always the best idea, though in this case it is. Hence, it is terminal only (thus you can also schedule it via cron).

    Added a lossless H.264 encoding example for anyone who wants to monkey with that.

    Thanks. Fixed. I wasn't sure if anyone actually read that section.

    The lossless presets have been removed upstream. They were out of date and slow.

    The old way:
    Code:
    ffmpeg -i input -vcodec libx264 -vpre lossless_ultrafast -threads 0 output
    The new way:
    Code:
    ffmpeg -i input -vcodec libx264 -preset ultrafast -crf 0 -threads 0 output
    or
    Code:
    ffmpeg -i input -vcodec libx264 -preset ultrafast -qp 0 -threads 0 output
    Either one should give the same result. If you used the old lossless_max preset the equivalent would be -preset veryslow -crf 0.

    Thanks a lot for the script! It saved my **** from headaches!

    Just in case someone is running Mint Ubuntu you have to edit two variables in the scripts.
    Just under:
    Code:
    DISTRO=( $(cat /etc/lsb-release | grep CODE | cut -c 18-) )
    Add:
    Code:
    DISTRO="natty";
    (or whatever version of Ubuntu your Mint corresponds to)

    And under:
    Code:
    DISTRIB=( $(cat /etc/lsb-release | grep ID | cut -c 12-) )
    Add:
    Code:
    DISTRIB="Ubuntu";

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

    Ok, so I've run the script and everything works, but when I do:

    ffmpeg -codecs

    I get (with a bunch of other stuff)

    D V D h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10

    I want to encode to H.264, is that possible?

    Thank,
    Greg

    Hi
    If this is on the list you can:-
    EV libx264 libx264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
