• Move converted file after each encode and delete original file on Ubuntu

  24 septembre 2018, par TinyTim

  I encode in batch and would like it to move the converted file to another directory after completing each encode and delete the original file.

  Here is my current bash I use to convert using FFMPEG.

  #!/bin/bash
  
  for i in *.mkv;
  
  do 
  
  #Output new files by prepending "X265" to the names  
  
  ffmpeg -threads 32 -i "$i" \
  
     -c:v libx265 -preset medium -crf 20 -pix_fmt yuv420p10le \
  
     -c:a ac3 -b:a 128k \
  
     -c:s copy \
  
     -map 0:0 \
  
     -map 0:1 \
  
     -map 0:2 \
  
     -x265-params "bframes=6:no-sao:frame-threads=3:numa-pools:8:slices=5:interlace=0:ref=6:rd=1:rect:analysis-reuse-mode:analysis-reuse-level=10:refine-mv:me=2:merange=64:rc-lookahead=60:b-adapt=2" \
  
     -max_muxing_queue_size 4000 X265_"$i"
  
  done

  Appreciate any help in advance.

• avformat/libopenmpt : Probe file format from file data if possible

  21 février 2018, par Jörn Heusipp

  avformat/libopenmpt : Probe file format from file data if possible
  When building with libopenmpt 0.3, use the libopenmpt file header
  
  probing functions for probing. libopenmpt probing functions are
  
  allocation-free and designed to be as fast as possible.
  For libopenmpt 0.2, or when libopenmpt 0.3 file header probing cannot
  
  probe successfully due to too small probe buffer, test the filename
  
  against the file extensions supported by the libopenmpt library that
  
  is actually linked, instead of relying on a hard-coded file extension
  
  list. File extension testing is also allocation-free and designed to
  
  be fast in libopenmpt. Avoiding a hard-coded file extension list is
  
  useful because later libopenmpt versions will likely add support for
  
  more module file formats.
  libopenmpt file header probing is tested regularly against the FATE
  
  suite and other diverse file collections by libopenmpt upstream in
  
  order to avoid false positives.
  FATE passes with './configure —enable-libopenmpt' as well as with
  
  './configure —enable-libopenmpt —enable-libmodplug'.
  libopenmpt probing adds about 5%..10% cpu time (depending on precise
  
  usage pattern and host CPU and compiler version used for libopenmpt)
  
  compared to all current internal FFmpeg probing functions combined in
  
  tools/probetest for all of its module formats combined (currently 41
  
  modules formats in libopenmpt 0.3.4 and 234 file formats in FFmpeg).
