  • FFmpeg AVI to MP4 transcode not playing fully in Quicktime

    11 août 2014, par Joel Kennedy

    I’m trying to transcode an AVI video to an MP4 stream on the fly using FFmpeg which can be watched on a webpage with a HTML5 video tag. I already know that MP4 isn’t designed for streaming, however it is possible if segmented so I’m still trying to use MP4 as it’s the method that I’ve found is best supported by multiple browsers.

    My stream plays fine in many browsers except for Safari on OS X, which is using Quicktime to play the HTML5 video.

    Quicktime only plays a second of the video, and then stops

    You can see in the image above that Quicktime only plays the video for a second, and then stops. I’ve tested the same video source in Google Chrome on OS X, and it continues playing fine even after a second has elapsed.

    I believe this is something to do with the set Duration in the tkhd and mdhd atoms ? User vbence described that "FFMpeg’s muxer will set the Duration in both tkhd and mdhd atoms to 0xffffffff for each track. This causes problems in some players (for example Quicktime will not play such files). You should find a tool and change it to zero (0x00000000)" in an answer here.

    Is there a way of getting FFmpeg to set a longer duration on the video to get Quicktime to continue playing it instead of stopping ? Because I’m transcoding on the fly, I wouldn’t want to use a separate tool apart from FFmpeg as in my situation I can’t transcode and save the video file, I have to transcode and pipe it to the client on request.

    The command that I’m using with FFmpeg to transcode the video is the following :

    ffmpeg -re -i
    http://www.example.com/video/stream?path=videopathhere -g 52
    -reset_timestamps 1 -vsync 1 -flags global_header -vcodec libx264 -strict -2 -f mp4 -b:v 512k -s 1280x720 -movflags frag_keyframe+empty_moov+faststart pipe :

    Any help or pointers in the right direction would be greatly appreciated.
