Supported Video Formats
The DragonFly only supports video playback with the RE2. The ARM Cortex processor on the RE2 has an integrated
Digital Signal Processor (DSP) which is capable of decoding certain video formats without loading the CPU. Other
formats are supported via software decoders which will consume CPU processing time. It is recommended that video
formats supported by the DSP are used, as this will give optimal system performance.
The following table shows current video format support:
Video Format
Software Decoder (CPU)
Hardware Decoder (DSP)
H264, High Profile
H264, Main Profile
H264, Base Profile
MPEG4, Part II
MPEG4, Xvid
MPEG4, DivX
MPEG2, High Profile
MPEG2, Main Profile
MPEG2, Base Profile
MPEG1
WMV
MJPEG
Video performance may be drastically reduced if the Video canvas is smaller than the video resolution.
H264 performance is drastically reduced if the display is rotated. For rotated displays, MPEG2 is recommended.
