    Re: HOWTO: Compile the latest ffmpeg and x264 from source

    Alright, I got it working. I ended up just downloading a slightly older one from the daily source tarballs and it worked just fine Now I'm stoked...I can get this working Thanks!

    You're right, the network was down. It's working now.

    Btw how do i optimize everything for quad core?(q6600) and auto upsize to 1680x1050 and enable all the features that makes the videos looks a lot better like sharpen, post processing etc?]

    If you're using x264 you can use the "-threads 0" option in your command to encode in parallel. Take a look at the "Additional Resources" section of the howto for examples and explanations.

    If you are updating to the newest ffmpeg you currently need to update your x264 also.

    http://lists.mplayerhq.hu/pipermail/...er/053527.html

    If you don't you will get this:

    libavcodec/libx264.c: In function `X264_init':
    libavcodec/libx264.c:165: error: structure has no member named `i_bframe_adaptive'
    make: *** [libavcodec/libx264.o] Error 1

    The developers have also checked in some x264 presets you might want to check out in the newest source code.

    ls -l ffmpeg/ffpresets/
    total 20
    -rw-r--r-- 1 root root 235 Sep 18 11:53 libx264-default.ffpreset
    -rw-r--r-- 1 root root 314 Sep 18 11:53 libx264-fastfirstpass.ffpreset
    -rw-r--r-- 1 root root 311 Sep 18 11:53 libx264-hq.ffpreset
    -rw-r--r-- 1 root root 322 Sep 18 11:53 libx264-max.ffpreset
    -rw-r--r-- 1 root root 295 Sep 18 11:53 libx264-normal.ffpreset

    Thanks for pointing out the presets, HolyRoses.
    If you dump them into ~/.ffmpeg/ then you can use them as follows:
    ffmpeg -i infile -vcodec libx264 -vpre hq -b 1M -bt 1M -threads 0 outfile.mp4
    From FFmpeg libx264 presets by Robert Swain. The link has more info and preset descriptions. You can edit the -b (bitrate) and -bt (bitrate tolerance) values from the example above to suit your needs.

    I think they are the exact same preset files actually.

    Looks like he just copied superdumps checkin's.

    Oh, I see now, he just shows you how to use them. The defaults file dont set any bitrates, they just set encoding parameters. I wasn't aware how to actually use them.

    I also think that -rc_eq 'blurCplx(1-qComp)' is hard coded into x264 now.
