This article mainly introduces "what is the function of HTML5 Flash video flv player". In daily operation, I believe many people have doubts about the function of HTML5 Flash video flv player. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the questions of "what function does HTML5 Flash video flv player have?" Next, please follow the editor to study!

Flv.js is an open source html5Flash video (FLV) player from the bilibili website, developed by pure native JavaScript (written by ECMAScript6), without the use of Flash. Its working principle is that Flv.js parses the flv file stream in JavaScript, transforms it into fmp4 in real time, feeds it to the browser through MediaSourceExtensions, and realizes the playback of FLV format video.

Flv player functions:

FLV container with H.264+AAC codec playback function

Multi-part segmented video playback

HTTPFLV low-latency real-time streaming

FLV plays real-time streaming through WebSocket.

Compatible with Chrome,FireFox,Safari10,IE11 and Edge

Very low overhead and hardware acceleration through your browser

Flv.js advantage

Because the browser uses hardware acceleration for native Video tags, it has good performance and supports high definition.

Both recording and live broadcasting are supported.

Get rid of dependence on Flash

Restrictions on flv players

The video encoding contained in FLV must be H.264, and the audio encoding must be AAC or MP3,IE11 and Edge browsers do not support MP3 audio coding, so the encoding used in FLV should be H.264+AAC. It is not a problem to make audio / video services compatible.

For recording, rely on native html5Video tags and MediaSourceExtensionsAPI

For live broadcasting, it depends on the playback technology required for recording and playback, and relies on a protocol in HTTPFLV or WebSocket to transmit FLV. HTTPFLV needs to pull data through streaming IO, and fetch or stream support streaming IO.

The flv.min.js file size is 164KB after gzip and 35.5 KB after the flash player gzip is about the same size.

Due to the dependence on MediaSourceExtensions, all browsers in iOS and below Android4.4.4 are not supported, which means that flv.js is basically not available on mobile devices.

At this point, the study on "what is the function of HTML5 Flash video flv player" is over. I hope to be able to solve your doubts.
