• Laravel FFMpeg - FFMpeg cannot edit existing files in-place

  28 septembre 2020, par wlaskovic

  After I wanted to upload a video in the queue was returned a failed job.

  


   [2020-09-25 13:24:25][125] Processing: App\Jobs\ConvertVideoForStreaming <br /> [2020-09-25 13:24:26][125] Failed:     App\Jobs\ConvertVideoForStreaming&#xA;

  


  So I've took from the DB failed_jobs table the response and run the following :

  


    C:\ffmpeg\bin\ffmpeg.exe -y -i "C:\wamp64\www\laravel-stream\storage\app/public\WF3UL8fJTSE7BMxa.mp4" -threads 12 -vcodec libx264 -acodec libmp3lame -b:v 500k -refs 6 -coder 1 -sc_threshold 40 -flags +loop -me_range 16 -subq 7 -i_qfactor 0.71 -qcomp 0.6 -qdiff 4 -trellis 1 -b:a 128k -vf "[in]scale=720:360 [out]" -pass 1 -passlogfile "C:\Users\wlask\AppData\Local\Temp\ffmpeg-passes5f6dd36a4519fd1fev/pass-5f6dd36a452c9" "C:\wamp64\www\laravel-stream\storage\app/public\WF3UL8fJTSE7BMxa.mp4"


  


  Which returned the following :

  FFmpeg cannot edit existing files in-place.

  


  


  This was returned after i've run the command from DB failed jobs table return.

  


  How should I solve this ?

  


• How do I access / stream an IP Camera (RTSP, ONVIF) from iOS using Swift

  24 avril 2015, par European

  I am a beginning Swift programmer with no Objective-C experience. I would like to create a UIView subclass which displays a video stream from an IP camera (RTSP, ONVIF).

  It looks like I will need to use the ffmpeg library http://sourceforge.net/projects/ffmpeg-ios/

  I did find one ffmpeg tutorial in Japanese ;-) http://qiita.com/tottokotkd/items/d9d376d5993961627aec

  Does anyone know of a tutorial on streaming an IP camera using Swift ?

• How do I include FFMpeg for development in a windows program ?

  4 août 2024, par Lama Mao

  I'm trying to follow a tutorial about using the FFMpeg libraries to extract frames from videos in C++ (by Bartholomew).

  


  In order to include the libraries, according to the tutorial, it is advised to use pkg-config to find the libraries and put them together so that CMake can include them. In the video he uses homebrew to install ffmpeg and somehow pkg-config is able to find the header files for ffmpeg (libavcodec, libavformat, libavdevice ...)

  


  The problem is I don't know how to get the ffmpeg libraries installed so that pkg-config can find them.

  


  On windows, I've tried installing the compiled windows binaries, and I've tried installing ffmpeg-full package using chocolatey. However, I fail to see where these header files are installed to.

  


  There's a ffmpeg folder in C:/ffmpeg/ but when I look in that there's no header files or libraries, just the binaries. Perhaps I need to clone the entire source project, but then how is pkg-config supposed to find them ? When I try and compile I get this output :

  


   Found PkgConfig: C:/Strawberry/perl/bin/pkg-config.bat (found version "0.26")

  The contents of C:/Strawberry/c/lib/pkgconfig seem to be a whole load of libraries none of which are from ffmpeg.

  


  In case the problem is in my CMakeLists file, here are the contents of the subdirectory file :

  What have I done wrong/am not understanding ?
