• Revision ac980b71cf : Improve sign consistency. Fix warning on windows : signed/unsigned mismatch on l

  23 avril 2013, par Johann

  Changed Paths :
   Modify /vp9/vp9_dx_iface.c

  
  
  Improve sign consistency.

  Fix warning on windows : signed/unsigned mismatch on lines 415, 454

  Comparison was between size_t data_sz >= int index_sz on 415 and
  unsigned int data_sz >= int index_sz on 454. Both might be changed to
  size_t but that would be tracing and replacing all comparisons is
  outside the scope of this change.

  In the rest of these two functions ensure unsigned values are used
  consistently.

• Revision 34324a98e7 : Restore vp9_asm_enc_offsets.c The previous commit 15255ee "Move dequant from BL

  26 avril 2013, par John Koleszar

  Changed Paths :
   Add /vp9/encoder/vp9_asm_enc_offsets.c

  
  
  Restore vp9_asm_enc_offsets.c

  The previous commit 15255ee "Move dequant from BLOCKD to per-plane MACROBLOCKD"
  removed the vp9_asm_enc_offsets.c file, but didn't update the various secondary
  build systems that special case these files. Restore it for now, to ensure any
  in-progress changes and builds continue working, to allow time to more carefully
  coordinate removal of these files.

• How to queue ffmpeg FIFO

  29 avril 2013, par Francois

  we build a service similar to youtube. Also converting runs fine with ffmpeg using this script from another post here :

  How do I set up an ffmpeg queue ?

  #!/bin/bash
  
  
  
  pipe=/tmp/ffmpeg
  
  
  
  trap "rm -f $pipe" EXIT
  
  
  
  # creating the FIFO    
  
  [[ -p $pipe ]] || mkfifo $pipe
  
  
  
  while true; do
  
  # can't just use "while read line" if we 
  
  # want this script to continue running.
  
  read line < $pipe
  
  
  
  # now implementing a bit of security,
  
  # feel free to improve it.
  
  # we ensure that the command is a ffmpeg one.
  
  [[ $line =~ ^ffmpeg ]] && bash <<< "$line"
  
  done

  This works pretty good when i send one by one to the named pipe. When i send more than one at same time the second one queues the terminal to the point the first one finished. if a try more than 2 the third one will not be transcoded.

  So i tried to workaround with background sending to get the terminal free (just drop the echo command and close the ssh connection) but this doesn't work, then i played around with screen -X but also no luck. Maybe someone has a good idea to deal this.

  What i wanna do is : Every uploaded video which is needed to transcode will send a echo to the named pipe. FIFO should match but not blocking the terminal. So i think i need something to really queue ffmpeg input.

  kindest regards
