• FFmpeg MSVC Compilation stuck

  10 mai 2017, par Earinor

  For several days now I try to build the FFmpeg Libraries. I’m using Windows7 64 Bit and MSVC2010. I followed this guide : https://trac.ffmpeg.org/wiki/CompilationGuide/MSVC

  I got rid of a view errors and configure is working finally. But when I try make, it runs for like half an hour and then gets stuck. It won’t proceed, I kept it running over night and nothing happend. I also tried different compiler options but it gets stuck every time at the same point.

  ffv1dec.o_converted.c
  
  d:\cpplibraries\ffmpeg-master\libavcodec\get_bits.h(308) : warning C4101: 're_cache' : unreferenced local variable
  
  d:\cpplibraries\ffmpeg-master\libavcodec\golomb.h(360) : warning C4245: '=' : conversion from 'int' to 'unsigned int', signed/unsigned mismatch

  I also tried setting up a minGW64 Msys2 Environment but have the same issue there.
  I also tried another setup but when I get rid of some errors I always get stuck at the exact same position.

  The cl.exe is running and is using memory but nothing happens.

  I also get a ton of warnings like conversions from int to unsigned int, Makro redefinitions, etc.

  I have no idea where to look to fix this, so I would appreciate some help.

• How to salvage a gigantic, possibly corrupt, AIFF file ?

  12 février 2012, par Ross Duncan

  Due to a Sound Track Pro glitch, I have a problematic AIF file. It plays fine in QuickTime Player, and is about 1 hour 50 mins long. However :

  • It's 3.81GB in size, whereas (I believe) AIF files are only supposed to be 2GB or smaller.
  • iTunes refuses to play it.
  • Logic Pro gives the error message "party-mix.aif is empty!" when I try to import it.
  • VLC will open and play the file, but it ends after an 1 hour (I guess this is the 2GB point).

  • Attempting to transcode using ffmpeg to Ogg gives the errors,

    [aiff @ 0x102051000] max_analyze_duration 5000000 reached at 5001333

    ....

    [pcm_s16be @ 0x10205a200] invalid PCM packet

    but the resulting file plays in VLC up till 1 hour, when it ends.

  • Attempting to transcode using ffmpeg to MP3 gives similar results as Ogg, except that the number of channels must reduced from 6 to 2. This is odd because it was a stereo project - where the extra 4 channels came from I have no idea.
  • There are a few places where the audio has been very noticeably sped up.

  My question : how can I transcode this frankenstein monster to MP3 without losing the second half ? I am running Mac OS 10.6.8.
