  • How do I properly format a request for ffmpeg to decode using a particular codec? [migrated]

    9 May 2013, by user2062660

    r3d is listed as a supported codec for decoding, however when I attempt to specify the r3d decoder, I get the error message "Unknown decoder". What is the correct manner of specifying a decoder codec?

    me$ ffmpeg -c r3d -i one.r3d one.mpg

    I want a background-image with that video on top of it and save it as an mp4-file. In the meantime the video has to be scaled and cropped
    I need a solution which can be automated and placed on a server, that is why i tried ffmpeg

    This is wat have at the moment:

    ffmpeg -loop 1 -f image2 -i background.png -r 25 -an -vcodec libx264 -b:v 1500k -vf "movie=test.mov[movie];[movie]scale=max(552\, 420*iw/ih):-1[OUT1]; [OUT1]crop=552:420[OUT2]; [0][OUT2] overlay=0:0 [out]" -s 552x420 -y output.mp4

    The problem is, somehow, the transparency is lost, and the background is black, instead of the underlying image. When i try the same ffmpeg command with a transparent FLV as input, it works, but i would like it to work without having to convert al source files first to another format

    Any help with this would be greatly appreciated !

    This is my current ffmpeg configuration:

  • ffmpeg export multichannel audio Stereo won't play [migrated]

    9 April 2014, by speedyrazor

    I am trying to export all audio channels from a multichannel quicktime file with ffmpeg which has the following audio configuration, but am unsure if the command below is correct. All the files look and play correct in Quicktime player except the L+R_Total.wav which refuses to play in Quicktime player or Final Cut but plays fine in VLC, so i'm sure my ffmpeg command is not correct for the stereo on Track 7. The Stereo file is about 1.8GB in size. Here is my track layout in the Quicktime file:

    Track 1 - mono
    
Track 2 - mono
    
Track 3 - mono
    
Track 4 - mono
    
Track 5 - mono
    
Track 6 - mono
    
Track 7 - stereo

    I am using:

    /Users/me/Desktop/python/ffmpeg/ffmpeg -i /Users/me/Desktop/test.mov -acodec pcm_s24le -map 0:1 -y Left.wav -acodec pcm_s24le -map 0:2 Right.wav -acodec pcm_s24le -map 0:3 Center.wav -acodec pcm_s24le -map 0:4 LFE.wav -acodec pcm_s24le -map 0:5 Left_Surround.wav -acodec pcm_s24le -map 0:6 Right_Surround.wav -acodec pcm_s24le -map 0:7 Left+Right_Total.wav

    Here is the printout from the terminal:

        MacBook-Pro:~ me$ /Users/me/Desktop/python/ffmpeg/ffmpeg -i /Users/me/Desktop/test.mov -acodec pcm_s24le -map 0:1 -y Left.wav -acodec pcm_s24le -map 0:2 Right.wav -acodec pcm_s24le -map 0:3 Center.wav -acodec pcm_s24le -map 0:4 LFE.wav -acodec pcm_s24le -map 0:5 Left_Surround.wav -acodec pcm_s24le -map 0:6 Right_Surround.wav -acodec pcm_s24le -map 0:7 Left+Right_Total.wav
