  • FFMPEG for iPhone recorded video encoding

    16 décembre 2011, par Sarah

    Hi found lots and lots of links for video encoding through ffmpeg 1,2,3,4 etc but they all start with using terminal commands but when i try to implement any on terminal like :

    git clone git ://github.com/lajos/iFrameExtractor.gitit says that-bash : git : command not found.

    Also as per my knowledge it is not possible to use terminal command on iPhone. Can anybody point out how to encode a video recorded through ffmpeg in mp4 format and also to reduce the size of the video ?Thanks in advance.

    EDIT :
    I am already implementing this method to resize my video and it successfully takes place and I am able to send the video on server but then on server side it's giving problem in retrieving the data and to use it.

    - (void)imagePickerController:(UIImagePickerController *)picker 
    
didFinishPickingMediaWithInfo:(NSDictionary *)info
    
{
    
    [self convertVideoToLowQuailtyWithInputURL:videoURL1 outputURL:[NSURL fileURLWithPath:videoStoragePath] handler:^(AVAssetExportSession *exportSession)
    
     {
    
         if (exportSession.status == AVAssetExportSessionStatusCompleted)
    
         {
    
             NSLog(@"%@",exportSession.error);
    
             printf("completed\n");
    
         }
    
         else
    
         {
    
             NSLog(@"%@",exportSession.error);
    
             printf("error\n");
    
         }
    
     }];
    
}
    

    
- (void)convertVideoToLowQuailtyWithInputURL:(NSURL*)inputURL 
    
                                   outputURL:(NSURL*)outputURL

{
    
    [[NSFileManager defaultManager] removeItemAtURL:outputURL error:nil];
    
    AVURLAsset *asset = [AVURLAsset URLAssetWithURL:inputURL options:nil];
    
    AVAssetExportSession *exportSession = [[AVAssetExportSession alloc] initWithAsset:asset presetName:AVAssetExportPresetLowQuality];
    
    exportSession.outputURL = outputURL;
    
    exportSession.outputFileType = AVFileTypeQuickTimeMovie;
    
    [exportSession exportAsynchronouslyWithCompletionHandler:^(void)

  • How the seek frame while playing video ?

    16 mars 2012, par sherman

    I try do this :

    void Java_ffvideo_company_com_NativeCalls_seekFrame(
    
        JNIEnv *env, jobject this, jint time) {
    

    

    
    if (avformat_seek_file(pFormatCtx, videoStream, 0,time,time, AVSEEK_FLAG_ANY) < 0)
    
        __android_log_print(ANDROID_LOG_DEBUG, "ERROR SEEK->>>",
    
                "av_seek_frame failed.");
    

    
    avcodec_flush_buffers(pCodecCtx);
    
}

    But the application crashes. Without avcodec_flush_buffers video seeking not correctly. How I can resolve this isssue ?

  • Need to get audio video structure for automation ffmpeg or ffprobe

    10 mai 2012, par Sapan Doshi

    I need to get video audio stream information in separate form.

    I have tried ffprobe and mediainfo, but they give full information which needs to be parsed.

    I think there could be option like, where I do not need to parse the full information and get required data.

    $ffprobe -XXX
    audio channels 8

    $ffprobe -YYY
    video_resolution 512x288

    Can anybody help with this.
