  • Given an x264 stream and an ogg vorbis stream, how do I make a muxed stream that mplayer/VLC can read ?

    14 avril 2012, par dascandy

    I'm confused and a bit stuck with this question. All I can find on Google is basic usage of transcoding software, which is not related to the question.

    I'm making a game and I'd like to include native capture ability to stream video. I would much like to stream this to a standard-ish client, such as VLC. It needs to be both in a format it recognizes and it needs to be multiplexed in order for this to work.

    My question therefore is, I know how to encode stuff from raw video frames to x264 (see also How to encode series of images into H264 using x264 API ? (C/C++) ). I know how to encode raw audio samples into ogg/vorbis. Now, how do I put one and one together for VLC ?

  • FFmpeg - create keyframes exactly each 25 frames

    1er octobre 2019, par Vlad Sineok

    So lately I have been using FFmpeg to convert videos to VP8 format for a Nintendo Wii game. There’s a problem I’ve ran into - the game plays the videos smoothly when there’s exactly 1 keyframe per second (the videos are at 25 fps). But some videos rendered with FFmpeg don’t have an exact gap of 25 frames between them (checked this with libwebm - if there are cues at 15.062 or something like that - the videos stutter, otherwise everything plays fine). So the question is : how do I force the keyframes to be generated exactly each 25 frames ? (The -g parameter doesn’t work)

  • Resources for learning Metal for Video Editing [on hold]

    28 septembre 2019, par Andrew Sawyer

    I am trying to build a video editing system in Swift for my iOS app. I assume that Metal would be the best system for this as it is extremely powerful. I am unsure where to start learning about Metal because most resources are related to game development.

    In V1 of my app I have used AVFoundation and an AVMutableComposition. However, in this version I need something more complex where I am able to do more effects, layering, etc.

    Is Metal the best way to do this or would another method (FFMpeg, Open GL, etc.) be better ?
    If so, what are the best resources to learn how to use Metal for this application ?

    Thank You !
