I just wanted to note that I've been researching this topic as well and found some 'hacky' solutions. I'm starting to think that the RPi just isn't up to the task of playing HTML5 video under Raspbian? Would installing one of the Ubuntu OS options for the RPi offer any benefit? I've increased the allocation of memory to the GPU, which hasn't offered any real improvement. webm file in iceweasel, which was able to manage ~1 frame of the video every ~3-4 seconds. The best result I've had has been in playing a ~10Mb local. webm on Midori, epiphany, iceweasel, etc.). I've tried 'testing' file format compatibility over at, but haven't been able to play any of the 'compatible' files on any of the 'compatible' browsers (I've tried both. I've searched this issue extensively online, and the 'new' epiphany web browser was/is supposedly the answer. I'm hoping to be able to use RPi's for system deployment, but I can't seem to find a suitable mix of browser/file format which allows for HTML5 video playback. # Stack-specific guidance # AMPįor animated content, use amp-anim to minimize CPU usage when the content is offscreen.My web-based application utilises HTML5 for various dynamic elements (img, video, etc).

You upload a GIF to the image CDN, and the image CDN returns an HTML5 video. Many image CDNs support GIF to HTML5 video conversion. # Use a service that converts GIFs to HTML5 videos Luckily, you can recreate these behaviors using the element.

They loop continuously (usually, but it is possible to prevent looping).

To use FFmpeg to convert my-animation.gif to a WebM video, run the following command in your console:įfmpeg -i my-animation.gif -c vp9 -b:v 0 -crf 41 my-animation.webm # Replace the GIF image with a videoĪnimated GIFs have three key traits that a video needs to replicate:

WebM videos are much smaller than MP4 videos, but not all browsers support WebM, so it makes sense to generate both. This tells FFmpeg to take my-animation.gif as the input, signified by the -i flag, and to convert it to a video called my-animation.mp4. To use FFmpeg to convert the GIF, my-animation.gif to an MP4 video, run the following command in your console:įfmpeg -i my-animation.gif my-animation.mp4 There are a number of ways to convert GIFs to video. Consider using MPEG4/WebM videos for animations and PNG/WebP for static images instead of GIF to save network bytes.

By converting large GIFs to videos, you can save big on users' bandwidth. Large GIFs are inefficient for delivering animated content. # Why you should replace animated GIFs with video See the Lighthouse performance scoring post to learn how your page's overall performance score is calculated.
