• Frame rate very high for a muxer not efficiently supporting it

  23 avril 2014, par DevDave

  I got an error when trying to run the following command with FFMpeg :

  -i "file1.mp4" -s 506x406 -b:v 2000k -ar 22050 "file2.mp4"

  FFMpeg was stuck converting this video, which was just a 7Mb .mp4 file, for hours and eventually I had to kill the process.

  The output error from FFMpeg is as follows :

  And it just pretty much carries on like that until when I killed the process.

  Can anyone explain to me what is going on here and what I can do to fix this ?

• ffmpeg live rtmp stream does not start to process for long time

  10 août 2013, par user1492502

  I have rtmp stream created by flash player in h264 but when i convert it to video or tumbnail using ffmpeg it some times works after very very long time and some time not work but if I create a stream with Flash Media live encoder on same FMS server the command below works fine. At the same time if I try the stream in player it works well and fine.

  I am using IP so DNS resolving issue is not possible either I think.

  ffmpeg -i rtmp ://xxx.xxx.xx.xx/live/bdeef2c065509361e78fa8cac90aac741cc5ee29 -r 1 -an -updatefirst 1 -y thumbnail.jpg

  Following is when it worked aftre 15 - 20 minutes

  when if i stop the stream it quickly creates a thumbnail file where as running stream is an issue.

• 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.
