  • MP4 videos in Firefox and IE not respecting rotation

    17 novembre 2015, par jnevelson

    We have a webpage that plays back a faststart MP4 in a <video></video> tag - pretty simple, and it works great in Chrome and Safari. However, it seems as though Firefox 36 and IE10 are not respecting the rotation of the video, so they end up playing either upside down or rotated 90*.

    Here is what ffprobe says about one of the videos :

    I’ve Googled around and haven’t found any information or bug reports on this, so I’m wondering if it’s something we’re missing or doing wrong. The video itself is only run through ffmpeg to make it faststart so we can stream it - no other encoding/transcoding is done.

    I’m hoping there’s a better solution than to return the rotation alongside the video and transform it via CSS - especially because it’s rotated properly in Chrome and Safari.

    Thanks !
