JMF 2.1.1 - Supported Formats
This page lists the media formats supported in the JMF 2.1.1 FCS implementation, the RTP formats this implementation can receive and transmit, and the capture devices that it supports.
Supported Media Formats
JMF supports audio sample rates from 8KHz to 48KHz. Note that cross-platform version of JMF only supports the following rates: 8, 11.025, 11.127, 16, 22.05, 22.254, 32, 44.1, and 48 KHz.
The JMF 2.1.1 Reference Implementation supports the media types and formats listed in the table below. In this table:
- D indicates the format can be decoded and presented.
- E indicates the media stream can be encoded in the format.
- read indicates the media type can be used as input (read from a file)
- write indicates the media type can be generated as output (written to a file)

RTP Formats
The JMF 2.1.1 Reference Implementation can receive and transmit the following RTP formats:
- R indicates that the format can be decoded and presented.
- T indicates that media streams can be encoded and transmitted in the format.

* JPEG/RTP can only be transmitted in video dimensions that are in multiple of 8 pixels.
** H.263/RTP can only be transmitted in 3 different video dimensions: SQCIF (128x96), QCIF (176x144) and CIF (352x288).
*** MPEG/RTP video can only be transmitted from pre-encoded MPEG content, i.e. from an MPEG-encoded file or MPEG enabled capture source. Real-time software MPEG encoding is not feasible for RTP transmission.
Capture Devices
The JMF 2.1.1 Reference Implementation supports SunVideo / SunVideoPlus capture devices on Solaris. On Windows, most capture devices that have VFW drivers are supported. On Linux, devices that have a Video4Linux driver are expected to work, but not extensively tested. The table below lists the capture devices known to work with this release.
