    by this code i am creating new object of news width video file and save that file into public/files

      public function store(Request $request, $type)
    
{ 
    
    $library_data = [
    
        'library_title' => request()->input('title'),

            }
    
        }
    
    }elseif (count($request->file('fileItem')) > 0 && !is_array($request->file('fileItem'))){

    then I dont know how use this codes to Create a frame from a video

    FFMpeg::fromDisk('videos')
    
->open('steve_howe.mp4')
    
->getFrameFromSeconds(10)
    
->export()
    
->toDisk('thumnails')
    
->save('FrameAt10sec.png');

    whate is ’videos’ in fromdisk and in my codes how use this parametrs

    I use this code `

    $new_file_object=$new_library_object->files()->create($file_data);
    
            $start = \FFMpeg\Coordinate\TimeCode::fromSeconds(5);
    
            $clipFilter = new \FFMpeg\Filters\Video\ClipFilter($start);
    
            FFMpeg::fromDisk('files')
    
                ->open($new_file_object->file_name)
    
                ->addFilter($clipFilter)

  • Build FFMPEG under Cygwin in Windows OS for Android

    8 juin 2017, par Jun Kim

    For the past couple days, I have been trying hard to build FFMPEG for a Android project on Windows Operating System using android-ndk-14d using Cygwin.
    I have followed many tutorials out there, and I ahve encountered so many errors while building FFMPEG using build_android.sh.

    Here are the steps that I have taken so far.

    I downloaded Cygwin and configured all the dependencies that I need for building FFMPEG.

    I opened ffmpeg-3.3.1/configure file with a text editor, and changed to the following lines.

    SLIBNAME_WITH_MAJOR='$(SLIBPREF)$(FULLNAME)-$(LIBMAJOR)$(SLIBSUF)'
    
LIB_INSTALL_EXTRA_CMD='$$(RANLIB) "$(LIBDIR)/$(LIBNAME)"'
    
SLIB_INSTALL_NAME='$(SLIBNAME_WITH_MAJOR)'
    
SLIB_INSTALL_LINKS='$(SLIBNAME)'

    my build_android.sh is as below

    #!/bin/bash
    
NDK=C:/~/ndk-bundle
    
SYSROOT=$NDK/platforms/android-21/arch-arm/
    
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/windows-x86_64

    I ran these commands

    dos2unix build_android.sh

    How to compile ffmpeg-2.5.3 on windows with android-ndk-r10d

    From the comments that were commented on the above link, it seems like it is
    easier to build FFMPEG in Linux/Unix OS. My first can be a dumb question. But If there is anyone who can guide me through this, i will be really appreciated it.

    If I build FFMPEG on Linux for Android, could I possibly copy or move those
    resulted output (The arm/lib folder contains the shared libraries, while arm/include folder contains the header files for libavcodec, libavformat, libavfilter, libavutil, libswscale etc.) to Windows OS and utilize them for
    my Android project ?

    Since my company only provides Windows OS for a project, I have to utilize them on Windows OS.

    Thank you for your time, and if there is any feedback that you can provide it will definitely be helpful.

    For the reference, here is my config.log

  • encoding with ffmpeg libx265 -pix_fmt gray gives unplayable vid

    9 juin 2017, par netjiro

    What am I missing ?
    I encode an old black and white film clip with ffmpeg libx265 passing -pix_fmt gray. The output is unplayable in both vlc and mplayer (linux), so I assume I’m missing something...

    encoding :

    ffmpeg -i clip.mkv \
    
    -c:v libx265 -preset slow -x265-params "crf=24" -pix_fmt gray \
    
    -c:a libopus -b:a 64k \
    
    -c:s copy \
    
    out.mkv

    vlc errors :

    [00007f8a3ddfe328] blend blend error: no matching alpha blending routine (chroma: RGBA -> GREY)
    
[00007f8a3ddfe328] core blend error: blending RGBA to GREY failed

    mplayer errors :
