  libavcodec/qsvenc : fix a memory leak problem
  "qf->frame" ref to input frame but it isn't released. av_frame_unref()
  
  is added before refering qf->frame to new frame to make sure the previous
  
  reference is released.

• how do I fix the permission problem so ffmpeg can write when run from a cgi-script ?

  7 juillet 2022, par NewtownGuy

  I have a shell script in Linux that runs ffmpeg for the purpose of converting video to a series snapshots in response to a command from apache2. The shell script is run from a perl script in /var/www/cgi-bin that is called by apache2. The conversion works fine when I run the shell script from the command line when I login as root. The problem is that ffmpeg cannot write its output when it's run from the cgi-script. With the exception of ffmpeg writing files, the shell script runs from the cgi-script just fine because I enabled it in /etc/sudoers and I run it with sudo. I have read several posts on the use of ffmpeg and setting permissions, and have tried the following without success :

  


  


  1. The full path to the snapshot files being written is given in the ffmpeg command

     


  


  2. I tried placing the shell script that runs ffmpeg into a root folder instead of the same folder, /var/www/cgi-bin, as the perl cgi script

     


  


  3. I gave the folder, /var/www/html/userName/video, where ffmpeg is to write its snapshots, www-data:root ownership instead of the original root:root, and I tried changing its write permission from 755 to 777.

     


  


  4. ffmpeg is installed in the default location, /use/bin

     


  


  


  How do I fix this ?

  


  Thank you in advance.

  Adaptive motion search control

  This commit enables adaptive constraint on motion search range for
  smaller partitions, given the motion vectors of collocated larger
  partition as a candidate initial search point.

  It makes speed 0 runtime of bus at CIF and 2000 kbps goes from
  167s down to 162s (3% speed-up), at 0.01dB performance gains. In
  the settings of speed 1, this makes the runtime goes from 33687 ms
  to 32142 ms (4.5% speed-up), at 0.03dB performance gains.

  Compression performance wise, it gains at speed 1 :
  derf 0.118%
  yt 0.237%
  hd 0.203%
  stdhd 0.438%
