• FFmpeg compile error

  7 octobre 2014, par CaptainCook

  I get an error when compiling my project ffmpeg. I followed this guide : TheGuide.

  When I execute the command make I get this error message :

  AS  libavcodec/arm/mlpdsp_armv5te.o
  
  libavcodec/arm/mlpdsp_armv5te.S:88:9: error: unknown directive
  
          .hword (60f - 0b) / 2, (61f - 0b) / 2, (62f - 0b) / 2, (63f - 0b) / 2, (64f - 0b) / 2
  
  ...
  
  make: *** [libavcodec/arm/mlpdsp_armv5te.o] Error 1

  I do develop on a MAC with OS X mavericks.

• avformat/mpegenc : Fix ever growing FIFO and infinite loop on error

  1er avril 2022, par Andreas Rheinhardt

  avformat/mpegenc : Fix ever growing FIFO and infinite loop on error
  Since the switch to the new FIFO API in commit
  
  ea511196a6c85eb433e10cdbecb0b2c722faf20d, the FIFO is always
  
  grown by the amount of data intended to be written into it
  
  even in case the FIFO has enough free space. Fix this by
  
  only growing the FIFO if needed and then only by the amount that is
  
  actually needed.
  The allocation errors that resulted from this uncovered another bug :
  
  The context is left in an inconsistent state in case the FIFO can't
  
  be grown, because the FIFO does not contain as much data as the sizes
  
  contained in the PacketDesc list claim. This led to an infinite loop
  
  in output_packet() (called from mpeg_mux_end()).
  Fix this by growing the FIFO before adding a new PacketDesc element,
  
  thereby preventing the context from becoming inconsistent.

• how to ignore or fix false 'unmet dependencies' error ?

  31 août 2014, par yy502

  OS: LMDE 201403

  I previously installed OpenShot (a video editing software), which depends on libmlt6, and libmlt6 depends on ffmpeg. The chain of dependencies auto-installed just fine.

  Today I compiled and installed the latest ffmpeg v2.3.3 and apt-get starts to complain :

  You might want to run 'apt-get -f install' to correct these:
  
  The following packages have unmet dependencies:
  
   libmlt6 : Depends: ffmpeg (>= 5:0.6.2~) but 2.3.3-1 is to be installed
  
  E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

  Well, I’m sure my compiled version of ffmpeg is newer than whatever version libmlt6 requires, but the package manager does not seem to understand the new version number. How can I ignore or fix false ’unmet dependencies’ error, please ?

  Thanks for your time !

  Edit :

  Executing apt-get -f install would install the ffmpeg from repository to /usr/bin/ and uninstall/overwrite my compiled version of ffmpeg in /usr/local/bin/... not really the solution I’m after...

  Edit2 :

  the auto fix of apt-get will remove my compiled version of ffmpeg as prompted below :

  sudo apt-get install -f
