  • html5 video client side optimization

    3 décembre 2014, par Withfriendship Hiox

    I am using flowplayer and doing video quality selection as in the following page :

    Flowplayer quality selection

    User choose a quality and plays the video like 160p, 260p, 530p etc depending on their Internet speed to load the video quickly. However in the server side I have to encode the original video using Ffmpeg into each of these resolutions and store them.

    So it doing like video_1234_low.mp4, video_1234_mid.mp4, video_1234_high.mp4, etc. and switch the source to that video depending on which the user selects. This consumes a lot of drive space for large videos.

    Is there any possibility to load the video quickly without storing these files. Dynamic conversion on demand is difficult because it takes time. I wonder is there any client side trick to reduce the download size and play low quality video.

  • Cannot invoke initializer for type ’UnsafeMutablePointer’ with an argument list of type ’(Int32 ?)’

    28 mars 2018, par Law Gimenez

    I am trying to implement some methods and pointers of ffmpeg to Swift but converting it to Swift is a little complex. What does this error mean ?

    Cannot invoke initializer for type ’UnsafeMutablePointer’ with an argument list of type ’(Int32 ?)’ ?

    Code is below

    let pictureFrameData = av_malloc(Int(numBytes))
    
                                var test = frame?.pointee.linesize.0.
    
                                av_image_fill_arrays(UnsafeMutablePointer(frameRGB?.pointee.data.0),
    
                                                     UnsafeMutablePointer<int32>(frame?.pointee.linesize.0)!,
    
                                                     pictureFrameData,
    
                                                     frameRGB?.pointee.format,
    
                                                     frameRGB?.pointee.width,
    
                                                     frameRGB?.pointee.height,
    
                                                     1)
    
</int32>

    the error is at this line UnsafeMutablePointer<int32>(frame?.pointee.linesize.0)</int32>
