• ffmpeg configure always returns "not found" when using sysroot and cross-prefix options - how to use them correctly ?

  5 août 2014, par user2212461

  I try to build ffmpeg with a cross-compiler. When setting the configure flags I am getting the following errors :

  WARNING: Compiler does not indicate floating-point ABI, guessing soft.
  
  build_it.sh: 29: build_it.sh: --sysroot=/home/android/android-ndk-r9/platforms/
  
      android-9/arch-arm/: not found
  
  build_it.sh: 32: build_it.sh.sh: --cross-prefix=/home/android/android-ndk-r9/
  
      toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86/bin/arm-linux-and
  
      roideabi-: not found

  The error message "not found" sounds like the paths dont exist but they are all correct and existing. How can I resolve this error ?

  build_it.sh :

  NDK=/home/android/android-ndk-r9
  
  SYSROOT=$NDK/platforms/android-9/arch-arm/
  
  TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86

• ffmpeg - 2nd audio stream added to video won't play

  21 octobre 2022, par Rafe

  I have a video that already contains an audio stream. I'm trying to add a second audio stream to that same video.

  


  ffmpeg -i input1.mkv -i input2.mp3 -map 0 -map 1:a -c:v copy output.mp4

  


  This seems very straightforward. But when I try to play the video, I can only hear one of the audio streams. This happens even if I reverse the order of the inputs, and regardless of whether I output to an mp4 or mkv file. It also happens if I map all of the streams from all of the input using -map 0 and -map 1, and it still persists if I use a wav file for the second input instead of an mp3

  


  When I use ffprobe to examine the output video, it's clear that there are three streams :

  


  Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'output.mp4':
  Metadata:

      vendor_id       : [0][0][0][0]

    Metadata:

  How do I get this video to play both of the audio streams ? This seems so simple, and it's driving me crazy that I can't figure it out.
