  • Cross device h264 compatible html5 video

    26 juin 2021, par mikkelam

    I'm trying to serve a large video of timelapses generated from a series of images.
    
Using FFmpeg I have encoded the video as an h264 mp4.

    


    ffmpeg -framerate 24 -i "/app/download/%d.jpeg" -c:v libx264 -crf 23 -preset fast -tune animation -report -vf "format=yuv420p" -y /app/output.mp4


    


    I'm running into compatibility issues where the videos are not playable on iOS (safari) as well as on Windows (all browsers except chrome). Where I'm getting the following error :

    


    Error Code: NS_ERROR_DOM_MEDIA_FATAL_ERR (0x806e0005) Details: mozilla::MediaResult __cdecl mozilla::WMFVideoMFTManager::ValidateVideoInfo(void): Can't decode H.264 stream because its resolution is out of the maximum limitation

    


    See the full FFmpeg log here : https://pastebin.com/QUEPh3q2

    


    I'm just looking for some resource or knowledge of how to encode my media for maximum compatibility while still preserving high quality and resolution.

    


    Problem :
    
Which options I should be using in FFmpeg to maximize compatibility ?

    


  • Convert a video to MP4 (H.264/AAC) with ffmpeg

    1er novembre 2022, par user176455

    If I don't make a mistake, Safari currently need MP4 (H.264/AAC) video encoded for the HTML5 <video></video> element.

    &#xA;&#xA;

    So I tried to convert a video to this format with ffmpeg. However when I enter the shell command ffmpeg -i video.flv video.mp4, the returned error is :

    &#xA;&#xA;

    &#xA;

    Seems stream 0 codec frame rate&#xA; differs from container frame rate :&#xA; 2000.00 (2000/1) -> 29.92 (359/12) Input #0, flv, from 'video.flv' :
    &#xA; Duration : 00:05:01.20, start :&#xA; 0.000000, bitrate : 66 kb/s&#xA; Stream #0.0 : Video : h264, yuv420p, 320x240 [PAR 1:1 DAR 4:3], 66 kb/s,&#xA; 29.92 tbr, 1k tbn, 2k tbc&#xA; Stream #0.1 : Audio : aac, 22050 Hz, stereo, s16 Output #0, mp4, to&#xA; 'video.mp4' :&#xA; Stream #0.0 : Video : mpeg4, yuv420p, 320x240 [PAR 1:1 DAR 4:3],&#xA; q=2-31, 200 kb/s, 90k tbn, 29.92 tbc&#xA; Stream #0.1 : Audio : 0x0000, 22050 Hz, stereo, s16, 64 kb/s Stream&#xA; mapping : Stream #0.0 -> #0.0
    &#xA; Stream #0.1 -> #0.1 Unsupported codec&#xA; for output stream #0.1

    &#xA;

    &#xA;&#xA;

    An AAC codec is required but I'm quite newbie with ubuntu and I dont really now how to fix this problem. I'm using Ubuntu 9.10 Karmik Koala (for amd64).

    &#xA;&#xA;

    Thank you very much. :)

  • ffmpeg transparent HVEC video from alpha matte and color video

    16 janvier 2023, par James

    I have an alpha.mp4 (alpha matte video) and a color.mp4 (color video). How do I use ffmpeg to make a transparent HVEC (.mov) video ?

    &#xA;

    I can combine with ffmpeg to make a .webm file following the instruction here :&#xA;https://www.unscreen.com/api under "Convert unpacked Pro Bundle to WEBM video with transparency"

    &#xA;

    I have a newer mac and should be able to use HVEC_videotoolbox from either these 2 videos or the .webm file created.

    &#xA;

    The closest I found was this which seems to generate a corrupt video that cannot be viewed in safari. Use FFmpeg to generate a movie with alpha channel from separate video and fill movies ? but
