  • 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 "

    configure : Check whether MSVC requires using the C89-to-C99 converter

    MSVC does support enough of C99 to work without the converter since
    
the 2013 version. Try to detect which version of the compiler in
    
the path needs to run the C99 converter or not. When the converter
    
is omitted, compilation time is reduced quite drastically.
    

    Prior to this, users could still use —cc="c99conv -noconv cl"
    
when running MSVC 2013 to achieve the same.
    

    This checks the version number instead of doing a normal compile
    
test, since this check needs to be done earlier in configure, before
    
the normal compile test helpers are usable.
