  • Ffmpeg and png watermark on OSX error

    28 juin 2012, par Stpn

    I am trying to add watermark with transparent background on OSX with ffmpeg.

    I am using this command :

    ffmpeg -i test.mpg -vf "movie=stuff.png, scale=100:100 [watermark]; [in][watermark] overlay=main_w-overlay_w:main_h-overlay_h-10 [out]"  out.mpg

    And I am getting this :

    I thought I am missing png support and I checked homebrew for libpng install, but it turn out png support is already included by Apple with OSX.

    Also I did

    ffmpeg -codecs list | grep -i png

    and I do have PNG support in ffmpeg :

  • 2 source videos in FFMPEG... how to map audio ?

    21 juin 2012, par dcoffey3296

    i am currently placing 2 videos side by side in FFMPEG. Here is the command :

    ffmpeg -i input.mov -vf "[in] scale=1280:720, pad=2*1280:720 [left]; movie=right.mov, scale=1280:720 [right]; [left][right]  overlay=1280:0 [out]" -b:v 1000k -vcodec libx264 -an sidebyside.mp4

    I now need to manage the audio. I keep trying to specify :

    -acodec libfaac -ac 2 -map 0:1 -map 0:2

    to take the 2 audio channels from the first input and use them. I keep getting the error :

    [aformat @ 0x7febf2e01fc0] auto-inserting filter 'auto-inserted resampler 0' between the filter 'src' and the filter 'aformat'
    
    [aresample @ 0x7febf2e02180] [SWR @ 0x7febf40dd000] Input channel layout isnt supported
    
Error opening filters!

    I'm looking for the best way to specify which video provides the audio ! Thanks for any advice !

    Here's the complete output :
