• How to Install FFMpeg on centos 6 in 2022?

  17 August 2022, by Ruben Fernandes

  a client of mine asked to add videos to their website, i decided to install FFMpeg on their server so whenever they upload a video, the service automatically generates the first frame for the preview and encodes them in webm.

  


  Sadly it seems to be impossible to install without having to compile it myself (which i don't really want to do as i have never done it before and don't want to risk breaking something in their server),

  


  The server is running cento6 but EVERY repository that provides the centos6 version of FFMpeg seem to use dependencies from dead hosts (they are offline and unreachable), every solution i find ends up with the same error like "Couldn't resolve host 'apt.sw.be'"

  


  I've changed yam repositories, installed apt-get to try with that instead of yam, disabled and enable repos like nux that seem to be very outdated, even followed posts that were published/updated recently like this but they all keep ending up with the the same "Couldn't resolve host..." when installing decencies.

  


  Is there any live and updated repo that provides a way to install FFMpeg for centos6 with yum or apt-get in 2022?

  


  Thanks

  


  EDIT
Following Romeo's tip about downloading the binaries, i managed to install it but in my case i needed a older 32 bit version to make it work (else i'd get Kernel too old):

  


  $ wget https://www.johnvansickle.com/ffmpeg/old-releases/ffmpeg-4.0.3-32bit-static.tar.xz
$ tar xvf ffmpeg-4.0.3-32bit-static.tar.xz
$ sudo mv ffmpeg-4.0.3-32bit-static/ffmpeg ffmpeg-4.0.3-32bit-static/ffprobe /usr/local/bin/


  


• avfilter/delogo: Fix show option when band is small

  28 September 2015, by Jean Delvare

  avfilter/delogo: Fix show option when band is small
  The code assumed that the outermost interpolated pixels were always in
  
  the fuzzy area defined by the band option. However if the band value
  
  is small, there may be no fuzzy area on a given plane. In that case,
  
  option show did not work, no rectangle was drawn (or only on the luma
  
  plane, depending on the band value and chroma plane subsampling
  
  factors.)
  Fix the problem by not making any assumption on where the outermost
  
  interpolated pixels will be.
  The new code was verified to produce the same result as the original
  
  code when the band value is not small.

• avcodec/frame_thread_encoder: Avoid allocations of AVPackets, fix deadlock

  7 February 2021, by Andreas Rheinhardt

  avcodec/frame_thread_encoder: Avoid allocations of AVPackets, fix deadlock
  Up until now, when doing frame thread encoding, each worker thread
  
  tried to allocate an AVPacket for every AVFrame to be encoded; said
  
  packets would then be handed back to the main thread, where the content
  
  of said packet is copied into the packet actually destined for output;
  
  the temporary AVPacket is then freed.
  Besides being wasteful this also has another problem: There is a risk of
  
  deadlock, namely if no AVPacket can be allocated at all. The user
  
  doesn't get an error at all in this case and the worker threads will
  
  simply try to allocate a packet again and again. If the user has
  
  supplied enough frames, the user's thread will block until a task has
  
  been completed, which just doesn't happen if no packet can ever be
  
  allocated.
  This patch instead modifies the code to allocate the packets during
  
  init; they are then reused again and again.
