    Re: FFmpeg Mplayer VLC - News & Howtos

    For those who do not follow the svn MPlayer there is an MPlayer release earlier this month: 1.1.1. A few details here:

    http://www.mplayerhq.hu/design7/news.html

    BTW I am considering adding a guide for MPlayer to the 'Tutorials' section, still watching to make sure there are no further changes to this subforum before I undertake this not small amount of effort...

    Text to Video

    found this
    Code:
    ffmpeg -chars_per_frame 200 -i input.txt output.mkv
    posted earlier by FakeOutdoorsman
    to turn text [.txt file]to video

    and thought how nice! but how to use it so that it can be used to post the resulting video on a video-sharing site (seriously) or that thoughtful ransom note [aargh!] in a way that is readable
    so here:


    Code:
    ffmpeg -chars_per_frame 200  -s hd720 -i NAME.txt -b:v 4000k  output.mkv && \
    ffmpeg  -i output.mkv -filter:v 'setpts=6.5*PTS' -b:v 4000k  outputslow.mkv \
    && rm output.mkv

    if you want slower try 7.0 or 7.5 or even slower 12.0 is a really comfortable reading speed

    As a trial I have placed an MPlayer compile guide back on these Forums:

    Howto: Build the svn MPlayer under the latest release version of Ubuntu
    http://ubuntuforums.org/showthread.php?t=2149564

    Interesting to see if it sinks or swims

    New filter: rotate. Now you can rotate your videos using any arbitrary angle. Note that the angle is expressed in radians, although you can have it convert radians to degrees for you.

    Rotate 33 degrees clockwise:
    Code:
    $ ffplay input.mkv -vf rotate="33*(PI/180)"
    hop.jpg
    (That is a hop plant if you're wondering).

    Examples from the docs:

    Apply a constant rotation with period T, starting from an angle of PI/3:
    Code:
    rotate=PI/3+2*PI*t/T
    Rotate the video, output size is chosen so that the whole rotating input video is always completely contained in the output:
    Code:
    rotate='2*PI*t:ow=hypot(iw,ih):oh=ow'
    Rotate the video, reduce the output size so that no background is ever shown:
    Code:
    rotate=2*PI*t:ow='min(iw,ih)/sqrt(2)':oh=ow:c=none

    Soon gonna be a time ffmpeg can walk on water or at least has a line of code that allows you to do that

    say
    Code:
    ffmpeg -i Jesus Copy [and for good measure]  -f///¹²³-457--0 --Galilee --feet--on--water //0
    or at the very least makes you breakfast .... it is amazing software

    I run Windows at work and I have downloaded a nice static version of FFmpeg that runs very nicely with Console 2. Not the same as Linux of course but the FFmpeg magic still produces great media files even on the limited platform of Windows . But as for a Big Mac I am a pretty dedicated vegan so that will not happen any time soon!

    ffplay can play itself:
    Code:
    $ ffplay /usr/bin/ffplay
    It might be loud, and your ffplay binary location will probably vary.
