  • FFmpeg compose, multi layers and filters, need kindly help 

    9 octobre 2019, par jadeshohy

    Pretty new to FFmpeg. We would like to use FFmpeg as a important part of an AR project.

    Currently, we find it is not easy for us.

    We want to compose the footages with FFmpeg.

    We got 5 layers, wanted to blend them with specific mode, like the things in After Effects.

    • layer-1/ [A.webm] video，vp9 codec, which has a transparent BG,has to be added as [normal mode]

    • layer-2/ [B.mp4] video, optical-flare things with black BG,has to be added as [screen mode]

    • layer-3/ [C.mp4] video, some motion graphic things with light BG,has to be added as [overlay mode]

    • layer-4/ [BG.MP4], backgound things, has to be added as [normal mode]

    After we blend those 4 (like pre-compose,use blend filter), we want to add another layer-5/[icon.png] which is the special icon.

    Layer-5 need to overlay the pre-compose. We have to overlay it at the special position (use overlay filter ?).

    Cause [icon.png] may change frequently. we want to deal with that after the 4 layer blending.

    But at the first step, when we set normal mode for layer-1 in blend filter, layer-1 [A.webm] lost the transparent BG，it gave us a black BG which block all other things.
    Blend filter can not handle the alpha channel of vp9 webm ?
    When we set the mode of layer-1 to screen mode,the translucent thing was not what we need.

    Could you please give us some commands to achieve the blend above ?

    The commands that are really work will be extremely useful for our FFmpeg initiation.

  • ffmpeg c++ seek performance

    30 juillet 2020, par thdemo

    I'm using ffmpeg for video playback, which works fine in itself, for many videos at once using HAP codec.

    


    The problem is when trying to play at faster speeds or reverse. The HAP codec only has full frames, so that should not be the problem. But apparently doing av_seek_frame and avcodec_flush_buffers is a big bottleneck. Not when playing a few videos, but I also want to be able to do it for 25 HD videos at once. Playing at normal speeds works fine for that many videos, but at higher speeds, the framerate becomes unusable.

    


    Is there a different way to handle playback speed and forward/backward direction anyone knows of that allows me to do this kind of playback at the same performance as normal playback ? A way to tell ffmpeg the playback speed and direction so that you don't need to seek and flush ?
