  • Efficient way to create variant playlists from mp4 for HLS

    3 mars 2021, par nnaj20

    I am totally new to video encoding and options, and just learned about Apple's HLS requirements.

    


    So far, I've been able to get something working for my iOS app. However, I find the entire process to be very slow and manual. Now, having to repeat this for several more locales (video translations), I can't imagine there isn't a better way.

    


    Controlling bitrate

    


    To have control over the bitrate, I use HandBrake to create a new .mp4 file with the appropriate video encoder setting, for each bitrate I want (192k, 400k, 1m, etc.). THEN, I move onto creating the playlists. This alone takes several minutes—is there a better way ? tsrecompressor seemed close, but it just streams to a local port and doesn't save any playlists.

    


    Creating playlists from MP4

    


    Then I use Apple's suite of command-line tools (mediafilesegmenter, variantplaylistcreator, mediastreamvalidator, hlsreport) to generate the playlists, combine into a master playlist, validate, etc. I suppose this part could be somewhat automated with a script. I've seen others use FFMPEG, but I think the latter 3 Apple tools would still need to be sequentially applied.

    


    Do you see anything that can be obviously optimized ?

    


  • Convert AVFrame to CVPixelBufferRef to use in function CVOpenGLESTextureCacheCreateTextureFromImage

    7 juin 2013, par hard gamer

    I've a custom video player on iOS platform, I read many threads for performance tuning about using CVOpenGLESTextureCacheCreateTextureFromImage API. But, this API is always used with Apple decoders, so as Apple decoders provide CVPixelBufferRef, I can not find any way to convert ffmpeg's AVFrame to CVPixelBufferRef...

    Can anyone guide me for this topic ?

    Is it possible to use CVOpenGLESTextureCacheCreateTextureFromImage API for AVFrames of ffmpeg ? If yes, how ?

  • Seeking Guidance on Audio Development Libraries for Playing Various Music Formats on iOS [closed]

    3 décembre 2023, par FaiChou

    I am exploring audio development and am overwhelmed by the numerous libraries available :

    


      

    • AVFoundation
    • 


    • MediaPlayer
    • 


    • AVFAudio
    • 


    • Audio Engine
    • 


    • CoreAudio
    • 


    • AudioToolbox
    • 


    • Audio Unit
    • 


    


    Which of these should I use to play both network or local music files (flac/wav/mp3/aac/wma/ogg) ? What are their specific roles ?

    


    My understanding is that I should use ffmpeg for demuxing to unpackage, then decode the stream to get PCM samples, possibly using Audio Engine for playback. Is this a software decoding method ? For Apple-supported formats like mp3, can I bypass ffmpeg for decoding ? Which library would be most suitable in this case ?

    


    Additionally, how do I extract metadata (song name, artist, cover, lyrics, etc.) from music files ? Apple's own solutions seem to support only ID3 or iTunes tags. How should I handle other formats like wav/flac ?

    


    The two links below are the resources I've referenced, but they seem outdated. My search for newer, reliable explanations has been fruitless.
