• Revision 73422d3b2d : Short circuit rate_block in block_rd_txfm. Don't run rate_block (cost_coeffs) i

  31 juillet 2015, par Alex Converse

  Changed Paths :
   Modify /vp9/encoder/vp9_rdopt.c

  
  
  Short circuit rate_block in block_rd_txfm.

  Don’t run rate_block (cost_coeffs) if distortion alone is enough to
  surpass best_rd.

  This decreases 2nd pass runtime on HD at speed 2 by about 2%. There is
  zero effect on output if tx_cache is removed.

• ffplay displays runtime error, yet still plays file

  11 mars 2016, par John Doe

  Im Working with pydub, and I’m using ffplay. For some reason, when the program runs i get this ’error’ :

   /usr/local/lib/python2.7/site-packages/pydub/utils.py:178: 
  
  
  
  RuntimeWarning: Couldn't find ffplay or avplay - defaulting to ffplay, but may not work
  
    warn("Couldn't find ffplay or avplay - defaulting to ffplay, but may not work", RuntimeWarning)

  However, it still plays the selected audio file.

  1. Is there a way to make this warning disappear, as it happens every time i play it ?
  2. If i can’t, is there anyway i can configure this so that it uses pyaudio to play the stream ?

• Video tube site on wordpress dedicated server mp4 only streams on android firefox

  9 mai 2015, par Steven Minix

  I have a video tube site that is quite popular and I am having an issue with my mp4 files streaming on android devices. When using Mozilla Firefox on android my videos play and seek perfectly. When using google chrome or default Android browser they do not play at all. I ran one of my videos through mp4box with a few settings and I got it to play on those browser in Android but they break when trying to seek. So at this stage the videos still play fine on Firefox in Android but now even though the video will start playing rather quickly on the other two browsers the videos will not seek properly as seeking will cause the video to break and restart itself. I am in a wordpress installation on a dedicated server.

  server specs:
  
  PHP 5.2.4 or greater
  
  MySQL 5.0 or greater
  
  PHP cURL extension
  
  PHP Zlib extension
  
  Unix-like OS (Windows is not supported)
  
  PHP 5.3, 5.4, 5.5 yes
  
  IonCube Loader 4.6.1 or above yes
  
  Mysql 5.0 or above and its support in PHP yes
  
  FFmpeg 1.0 or above with libx264, libavfilter and AAC codec (libfaac, libfdk_aac or native ffmpeg aac codec) yes
  
  cURL and its support in PHP yes
  
  Apache + mod_rewrite + (MultiViews option disabled) yes, not sure about multi views, please ask how this is done.
  
  Zlib library yes
  
  XML extension yes
  
  GD2 with true type font (required!) yes
  
  Ability to exec PHP from CLI using exec() command yes
  
  PHP register_globals off yes
  
  PHP magic_quotes_gpc off yes
  
  PHP safe_mode off yes
  
  PHP file_uploads on yes
  
  PHP allow_url_fopen on yes

  The files are MP4 with the meta data at the front of the file and playing in the standard wordpress video player(or any html5 based player as I have tried quite a few and all have the same result)

  I had to ask my server admin to install ffmpeg for my streaming is it possible they did not add the right commands ?

  I have no idea what my videos are doing on Apple devices but I assume it is okay since Google Analytics shows a low bounce rate from that devices.

  If any issue is on service side I want to contact them armed with facts. I appreciate your help in this matter.

  The few things I tried with the mp4 that got them to play but still not seek properly were running them through mp4box with no special settings and simply remuxing them. I also tried a couple special settings like adding a hint track and other things none resulted in the file streaming properly in chrome or default android browser. AGAIN my files stream fine on all desktops and in FIREFOX on android but DO NOT work in chrome on android or default android browser.
