Video Formats

We support the following video formats. You can deliver your video with any of them.


HTTP Live Streaming (also known as HLS) is an HTTP-based adaptive bitrate streaming communications protocol developed by Apple Inc. Support for the protocol is widespread in media players, web browsers, mobile devices, and streaming media servers. Gumlet also recommends using this format for seamless video delivery and playback.

HTTP Live Streaming provides ways for video players to adapt to unpredictable network conditions changes without causing user-visible playback stalling. For example, on an unreliable wireless network, HLS allows the player to use a lower quality video, thus reducing bandwidth usage.

Any modern video player is capable of playing HLS stream produced by Gumlet. Most web players, iOS and Android devices support HLS playback. It's best choice for universal playback.


Dynamic Adaptive Streaming over HTTP (DASH), also known as MPEG-DASH, is an adaptive bitrate streaming technique that enables high-quality streaming of media content over the Internet delivered from conventional HTTP web servers. Similar to HLS.

DASH is not supported in Apple products like iOS and Safari. This makes the HLS perfect choice as universally supported streaming standard.


MPEG-4 Part 14 or MP4 is a digital multimedia container format most commonly used to store video and audio. It allows streaming over the Internet. This is the most widely supported format and requires no extra player or javascript.

The downside of MP4 is that adaptive bitrate streaming is not supported, hence there will be subpar user experience and large data transfers.
