  • Errors while building customised ffmpeg4.1 with libavcodec.58 and opencv

    8 juillet 2019, par geo-freak

    I am trying to build my customised ffmpeg of version 4.1. As we know that ffmpeg4.1 needs libavcodec.so.58 and other related libraries(newest). I have some functions related to opencv in my code such as cvLoadImage and other. I updated the libopencv-highgui-dev, libopencv_core-dev and libopencv_imgproc-dev libraries. When I run the makefile I got the following errors,

    I have clearly linked the newest libraries and included them in my makefile. Errors list suggesting me that, libopencv-highgui.so is pointing to libavcodec.57 version api’s. Has opencv not upgraded to support libavXX.so.58 libs ? or I am doing anything wrong here.

    Please help me with this, or any suggestions would be helpful.

  • Building a CLI Batch for Windows upon usage of FFmpeg Video Conversor

    24 juillet 2020, par blueskuc

    Here what ive done for WINDOWS users :

    


    but getting an error if any can help !

    


    Check code :

    


    @echo off
set /P file="Say the FILE EXTENTION.: "

(for %i in (*.%file%) do (
    @echo ffmpeg.exe -i %i -vf scale=480:320 %i-.mp4 > %file%-em-lista.bat
    
    ))

echo Now wait Batch File Created Started Convert, make sure having ffmpeg installed at system32
start %file%-em-lista.bat


    


    Also I noticed i got stucked, it does works out in CMD typed dirrecly :

    


    Give a check, this command will enumerate all txt files at your folder :

    


    FOR %f in (dir /b *.txt) do (echo %f)


    


    Guess its a not know code declaration or concatenation, im already at the 3th day trying it out of sevaral ways.

    


    @echo off

set /P fext="SAY VIDEO FORMAT.: "
set /P xpath="SAY FOLDER OR VIDEO LOCATION FOR BATCH CREATION.: "
set current_dir=%xpath%

echo "Your Current Directory IS: %current_dir%"

FOR /f %i in (dir /b *.%fext%) do (
        
        @echo ffmpeg.exe -i %i -vf scale=480:320 -v error -hwaccel cuda -hwaccel_device 0 %i.mp4 > %xext%-em-lista.bat
        
        )
echo "Starting Conversions"
start %fext%-em-lista.bat 
echo Wait Conversions Finish
end


    


    Since yesterday : UPDATED code working Stable inside Videos Folder 24/07/20

    


    @echo off

echo ###Set the VideoExample.Ext you are going to converto to MP4####

set /P file="Say the FILE EXTENTION.: "


REM going to make a if later for not Nvidia GC cuz of CUDA Aceleration not found in any Freeware Software REM

(for %%i in (*.%file%) do @echo ffmpeg.exe -v error -hwaccel cuda -hwaccel_device 0  -i %%i -acodec copy -f mp4 -ac 2 -vf scale=480:320 %%i.mp4) > %file%-to-mp4-em-lista2.bat

echo Wait Process Finish *-*
start %file%-to-mp4-em-lista2.bat


    


    As far now, need improvements for

    


    Options :
[1] make a default folder for IN and OUT converted Videos
[2] make a inseted DIR-PATH workable IN and OUTPUT Videos

    


    Videos to Audio and sort of FFMPEG options as we like.

    


  • 'imported-lib - NOTFOUND' in building ffmpeg 3.2 for android studio 2.2

    17 février 2017, par mdang

    I am trying to build and use ffmpeg for Android. My Andoid Studio version is 2.2.2 and ffmpeg is 3.2. Following Android documentation on how to import rebuild library, I think I got the setting right but kept on getting this error

    ninja: error: 'avcodec-NOTFOUND', needed by '../../../../build/intermediates/cmake/debug/obj/armeabi-v7a/...

    This is the setting

    add_library( avcodec SHARED IMPORTED )
    
add_library( avdevice SHARED IMPORTED )
    
add_library( avfilter SHARED IMPORTED )
    
add_library( avformat SHARED IMPORTED )
    
add_library( avutil SHARED IMPORTED )
    
add_library( swscale SHARED IMPORTED )
    

    
set_target_properties( avcodec
    
                        PROPERTIES FFMPEG_LIB_IMPORTED_LOCATION
    
                        libs/ffmpeg/${ANDROID_ABI}/lib/libavcodec.so
    
                        )
    
set_target_properties(  avdevice
    
                        PROPERTIES FFMPEG_LIB_IMPORTED_LOCATION
    
                        libs/ffmpeg/${ANDROID_ABI}/lib/libavdevice.so
    
                        )
    
set_target_properties( avfilter
    
                        PROPERTIES FFMPEG_LIB_IMPORTED_LOCATION
    
                        libs/ffmpeg/${ANDROID_ABI}/lib/libavfilter.so
    
                        )
    
set_target_properties( avformat
    
                        PROPERTIES FFMPEG_LIB_IMPORTED_LOCATION
    
                        libs/ffmpeg/${ANDROID_ABI}/lib/libavformat.so
    
                        )
    
set_target_properties( avutil
    
                        PROPERTIES FFMPEG_LIB_IMPORTED_LOCATION
    
                        libs/ffmpeg/${ANDROID_ABI}/lib/libavutil.so
    
                        )
    
set_target_properties( swscale
    
                        PROPERTIES FFMPEG_LIB_IMPORTED_LOCATION
    
                        libs/ffmpeg/${ANDROID_ABI}/lib/libswscale.so
    
                        )
    

    
# Specifies a path to native header files.
    
include_directories(
    
                    libs/ffmpeg/${ANDROID_ABI}/include
    
                    )
    

    
target_link_libraries( # Specifies the target library.
    
                       native-lib
    

    
                       # Links the target library to the log library
    
                       # included in the NDK.
    
                       avcodec avdevice avfilter avformat avutil swscale
    
                       ${log-lib}
    
                        )

    If I specify the full library name, libavcodec.so..., the error would go away.

    target_link_libraries( # Specifies the target library.
    
                       native-lib
    

    
                       # Links the target library to the log library
    
                       # included in the NDK.
    
                       libavcodec.so libavdevice.so libavfilter.so libavformat.so libavutil.so libswscale.so
    
                       ${log-lib}
    
                        )

    I wonder if anyone encountered similar issue or know why the compilation behaves this way.
