• FFMPEG - Pipe Different HLS Resolutions to S3

  17 juillet 2019, par Mike

  I’m trying to save all my HLS output files directly to S3. As you can see in the code, I’m saving output files for many different sizes and bitrates. My issue is I can’t figure out how to save the files onto S3. I have managed to get this working on an EC2 instance where I save all the files on the same server, but once I try to use aws cli it fails. I can also get this working if it’s just one resolution.

  I’m guessing it has something to do with piping multiple aws cli commands since I can see it tells me Unknown options:, but I don’t see any other way of doing this.

  Also, I’m using the -progress flag so I can show the transcode progress to the user, can I pipe that directly to S3 as-well ?

  Note, the code below has been formatted to make it readable, it obviously doesn’t look like this when ran on the server.

  avcodec/vc2enc : Simplify writing dirac golomb codes
  The earlier code used a loop to determine the number of bits used
  
  and called ff_log2() on a power of two (and it would be easy to
  
  keep track of the exponent of said power-of-two) ; neither GCC nor
  
  Clang optimized the loop away or avoided the ff_log2().
  
  This patch replaces the loop and the log2 with a single av_log2().

  2 octobre 2014, par Manfred Georg

  lavc : specify the behavior of av_lockmgr_register on failure.
  The register function now specifies that the user callback should
  
  leave things in the same state that it found them on failure but
  
  that failure to destroy is ignored by the library.  The register
  
  function is now explicit about its behavior on failure
  
  (it unregisters the previous callback and destroys all mutex).
