  • iPad Doesn't Render H.264 Video with HTML5

    5 octobre 2011, par jgoldberg

    I have some H.264-encoded videos which render in HTML5 correctly in the web browser, but do not render correctly on the iPad. When I use a H.264 video I downloaded off the internet, my video renders correctly on the iPad, so it is not an HTML problem.

    Here is the ffmpeg info about my videos —

    My original .mov video :

    Seems stream 1 codec frame rate differs from container frame rate : 6000.00 (6000/1) -> 30.00 (30/1)

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'a_video.mp4' :

    Metadata :

    major_brand     : qt  
    
minor_version   : 537199360
    
compatible_brands: qt  

    Duration : 00:00:42.74, start : 0.000000, bitrate : 220 kb/s

    Stream #0.0(eng): Audio: aac, 44100 Hz, stereo, s16, 94 kb/s
    
Stream #0.1(eng): Video: h264, yuv420p, 762x464, 122 kb/s, 30 fps, 30 tbr, 3k tbn, 6k tbc

    After using Handbrake to convert my .mov to a mp4, yet doesn't render on the iPad :

    Seems stream 0 codec frame rate differs from container frame rate : 180000.00 (180000/1) -> 29.97 (30000/1001)

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'a_video.m4v' :

    Stream #0.0(und) : Video : h264, yuv420p, 752x464 [PAR 381:376 DAR 381:232], 35 kb/s, PAR 145161:141376 DAR 145161:87232, 29.97 fps, 29.97 tbr, 90k tbn, 180k tbc
    Stream #0.1(eng) : Audio : aac, 44100 Hz, stereo, s16, 128 kb/s

    Here is a .mp4 I found online which does render on the iPad :

    Seems stream 1 codec frame rate differs from container frame rate : 180000.00 (180000/1) -> 25.00 (25/1)

    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'a_video_3_emu.mp4' :

    Metadata :

    minor_version : 1
    compatible_brands : M4VPM4A mp42isom
    encoder : CoreMediaAuthoring 677, CoreMedia 420.17, i386

    Duration : 00:01:38.01, start : 0.000000, bitrate : 1023 kb/s

    Stream #0.0(und) : Audio : aac, 32000 Hz, mono, s16, 97 kb/s
    Stream #0.1(und) : Video : h264, yuv420p, 480x360 [PAR 1:1 DAR 4:3], 914 kb/s, 25 fps, 25 tbr, 90k tbn, 180k tbc

    Does anyone see something wrong with the way I am encoded my videos ?

    Edit

    At first my theory was that the iPad was sensitive to different container formats ; but that appears not to be the case. I took a video which does render correctly on the iPad and converted it to a .mov, and it still played correctly on the iPad. So there must be a problem with how the iPad deals with the underlying H.264 stream.
