  • Why MediaArea_MediaInfo, AlturosDestinations_Alturos.VideoInfo and Xabe.FFmpeg work in C# console and winforms applications but not in UWP apps ?

    15 octobre 2020, par Morteza

    I want to get video files metadata. I used MediaInfo, AlturosVideoInfo and Xabe.FFmpeg. AlturosVideoInfo and MediaInfo return null but Xabe.FFmpeg returns an exception that says Invalid File (Can't open the file).

    &#xA;

    I think the problem is limitations in accessing files in UWP, but I added the folder that contains video files to FutureAccessList and even used FileOpenPicker.

    &#xA;

    How can I use these tools to get video metadata in UWP ?

    &#xA;

    Thank you

    16 octobre 2019, par axita.savani

    Using FFmpeg lastest version ("Ada") with native code and write command in android .cpp file below it’s very simple function VideogetDuration() :

    #include 
    
#include <string>
    
#include <iostream>
    
#include <android></android>log.h>
    
#include 
    

    
extern "C" {
    
#include <libavutil></libavutil>timestamp.h>
    
#include <libavformat></libavformat>avformat.h>
    
#include <libavutil></libavutil>display.h>
    
}
    

    
    /***
    
     *
    
     * @param input - the absolute path to file
    
     * @returns the duration of file in seconds
    
     *
    
     */
    
    extern "C"
    
    JNIEXPORT jint JNICALL
    
    Java_com_ffmpegjni_videoprocessinglibrary_VideoProcessing_getDuration(JNIEnv *env,
    
                                                                          jobject instance,
    
                                                                          jstring input_) {
    
        av_register_all();
    
        AVFormatContext *pFormatCtx = NULL;
    
        if (avformat_open_input(&amp;pFormatCtx, jStr2str(env, input_), NULL, NULL) &lt; 0) {
    
            throwException(env, "Could not open input file");
    
            return 0;
    
        }
    

    

    
        if (avformat_find_stream_info(pFormatCtx, NULL) &lt; 0) {
    
            throwException(env, "Failed to retrieve input stream information");
    
            return 0;
    
        }
    

    
        int64_t duration = pFormatCtx->duration;
    

    

    
        avformat_close_input(&amp;pFormatCtx);
    
        avformat_free_context(pFormatCtx);
    
        return (jint) (duration / AV_TIME_BASE);
    
    }
    
</iostream></string>

    when this value returns 0 value either the wrong value.
