• av_interleaved_write_frame() unknown error when streaming WebM

  16 avril 2015, par user1475135

  I’m following a guide to live WebM streaming through FFMpeg / FFServer and running into an interesting error. I have tried using a DirectShow webcam source, and also an existing WebM (finite length) video using -vcodec copy. Initially, both will manage to connect to the FFServer (I can see the POST 200 OKs to /feed1.ffm), and maybe even send a frame or two, but then FFMpeg crashes with av_interleaved_write_frame(): Unknown error. (Meanwhile, FFServer appears to be fine.)

  This appears to be an unusual variant of the error - normally it’s more common to get, say, av_interleaved_write_frame(): I/O error (which indicates file corruption). Has anyone seen this error, and better yet, can anyone tell me how to fix it ?

  FFMpeg commands

  • ffmpeg -re -i univac.webm -vcodec copy -acodec copy -f webm http://[my server]/feed1.ffm
  • ffmpeg -f dshow -i video="[my dshow source]" -f webm http://[my server]/feed1.ffm

  FFserver command

  ffserver -f ffserver.conf

  ffserver.conf

  This is only a slight variation in the one provided in the aforementioned guide.

• FFMPEG for APACHE 2.4.6 (x64), PHP 5.5 (x64), MYSQL 5.6 (x64) on WINDOWS 8 (x64) MACHINE

  FFMPEG for APACHE 2.4.6 (x64), PHP 5.5 (x64), MYSQL 5.6 (x64) on WINDOWS 8 (x64) MACHINE

  I need to install FFMPEG on my windows 8 machine running DRUPAL ZEN custom theme. Can someone tell me where I can get the right dll files for this purpose ? If I have to compile them myself, can someone please give me step by step instructions for how to do so ? I have searched endlessly for these dlls for days now and I have no instructions for creating what i need manually. I have a windows machine running minGW.

  I already tried using the FFMPEG dlls that are out there on teh internet but my PHP-APACHE installations seem to be unable to properly detect the FFMPEG libraries (i added php_ffmpeg.dll to EXT folder, and the rest of hte DLLs to the WINDOWS/SYSTEM32 folder).

  I am running the following versions of PHP and APACHE. Thank you very much in advance for any help you can offer me.

  PHP Version 5.5.1
  System Windows NT 6.2 build 9200 (Windows 8 Business Edition) AMD64
  Build Date Jul 18 2013 11:04:03
  Compiler MSVC11 (Visual C++ 2012)
