  • Changing portrait videos to landscape aspect with latest ffmpeg release is breaking

    19 décembre 2016, par zeal

    I am having an issue scaling videos recorded in portrait with the latest version of ffmpeg (2.1). This worked fine in a previous version, but I need the lastest version to fix a different issue.

    I am trying to take any video passed and make it 852 wide by 480 high. It works fine when converting videos that are wider then tall, but when the video is taller then wide it corrupts the video. It actually adds a letter box to the top and bottom, rather then left and right. Also, the meta data shows it as the correct height & width, but its wrong when played in windows.

    Here are the parameters I am using.

    ffmpeg -i INPUT -s 852x480 -r 30 -aspect 1.775 -b:v 2000000 -vcodec mpeg4 -vf "scale=iw*min(852/iw\,480 /ih):ih*min(852/iw\,480 /ih),pad=852:480 :(852-iw)/2:(480 -ih)/2" -ac 2 -b:a 128k -ar 44100 -y OUTPUT

    Console output from ffmpeg -i INPUT -r 30 -b:v 2000000 -vcodec mpeg4 -vf "scale=852:480" -ac 2 -b:a 128k -ar 44100 -y OUTPUT :

    C:\Lib>ffmpeg -i "d\ca96cd13-2995-4794-b753-22be3b918659.mov" -r 30 -b:v 2000000 -vcodec mpeg4 -vf "
    
scale=852:480" -ac 2 -b:a 128k -ar 44100 -y "d\portx.mp4"

  • ffmpeg minimal requirements configuration for encoding and decoding h264 files

    14 novembre 2013, par TheSquad

    I'm trying to compile ffmpeg with minimal requirements in order to encode/decode with h264.

    So far my command line configuration is :

    ./configure --disable-yasm --disable-everything --enable-encoder=libx264 --enable-encoder=libfaac --enable-decoder=h264 --enable-muxer=h264 --enable-demuxer=h264 --enable-parser=h264 --enable-protocol=file

    once compiled, I try this :

    ./ffmpeg -i ~/Dropbox/TestFile.mov -vcodec libx264 test.mp4

    but I get an error :

[NULL @ 0x7fd999802e00] Unable to find a suitable output format for 'test.mp4'
    
test.mp4: Invalid argument

    This is probably coming from the fact that I have forgot something to enable on the ffmpeg configuration... But I can't found out what.

    The test file is a video got from iPhone 4S Camera.

  • FFMPEG iOS 7 Library

    25 mars 2014, par Destiny Dawn

    I've tried reading many tutorials.
    I've spent hours on google, and stackoverflow trying answer.
    So far I've read : Trying to compile the FFMPEG libraries for iPhoneOS platform with armv6 and arv7 architecture FFMPEG integration on iphone/ ipad project and https://github.com/lajos/iFrameExtractor few of the many.

    I'm trying to build this library for iOS 7/Xcode 5 compatibility but it's not working.
    A common error I'd get is :

    Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
    
yasm/nasm not found or too old. Use --disable-yasm for a crippled build.
    

    
If you think configure made a mistake, make sure you are using the latest
    
version from Git.  If the latest version fails, report the problem to the
    
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
    
Include the log file "config.log" produced by configure as this will help
    
solving the problem.

    I'd also get many more once that is finished. Such as :

    rm: illegal option -- .
    
usage: rm [-f | -i] [-dPRrvW] file ...
    
       unlink file
