iOS failing to play MP4

Foliovision › Forums › FV Player › Bug Reports › iOS failing to play MP4

  • bruno 1 year, 2 months ago

    Hello,

    i’ve been reported that videos won’t play on iOS and iPad devices with error message ‘html5: Video file not found’. Issue is on both Safari or Firefox. Apparently no issue on Desktop
    example >> (redacted)
    How to fix this ?

    Thank you

    Hello Bruno,

    On your test page the video is MP4.

    Some MP4 videos do not play on iOS, although we were not able to find the root cause of the issue. When this issue occurs then the video won’t play even if you open it directly in the iOS web browser. That means it fails to play even when FV Player is not used.

    However I did not run into issues with your MP4 video and it played on your test page as well. This should be tested with the exact video that is failing, please submit it using our Video Checker too: https://foliovision.com/player/troubleshooting/how-to-use-video-checker

    Thanks,
    Martin

    Hi Martin and than you for you reply.

    Here is the report from the video checker:

    Video meta data: moov-atom not found at the start of the file. Please move the meta data to the start of video, otherwise it might be slow to start. Plese check the "MP4 and metadata" in Video Encoding for HTML 5.

    I replaced the video on my test page by an actual reported video that doesn’t play in iOS >> (redacted)
    Let me know if it helps identifying the issue.

    Thank you

    Hello Bruno,

    When I play your video in Chrome(ium) I can see that it loads the video ending first and only then it starts playing the video.

    So the error detected by our Video Checker is real:

    moov-atom not found at the start of the file. Please move the meta data to the start of video, otherwise it might be slow to start.

    I tried on iPhone with Safari browser without using FV Player and it would fail to play that video. It probably does not have such strong loading routine as Chrome and in some cases if the moov meta data is not present at the start of the file it just fails to play the video.

    Thanks,
    Martin
