Pure Java Video Format without native Libraries

is there something like a video format/codec/container that works in java without the use of any native libraries?

i know there is that java media framework开发者_如何学运维, but it seems a bit outdated.

Cortado streaming applet distributes a theora codec written in java. It is also part of FMJ.

There is an open source library called JCodec ( http://jcodec.org ) that implements a couple of popular formats and codec in pure java. These include: H.264 ( AVC ), MPEG 1/2, Apple ProRes and JPEG. Formats include: MP4, Matroska, MPEG PS and MPEG TS.
The documentation is virtually non-existent though.

You should check out the Wikipedia article about the JMF.
