E412
Introduction
The E412 is a compact H.264 encoder. It is a second generation encoder of the E12/E110/E112
encoders. The main differences are:
•fast boot up: only 2 seconds
•smaller and lower power consumption
•flexible: add your host system for stream formatting "
- a compact host system in E412 form factor is planned (it will install below E412)
Key features
•video input: standard size HDMI connector
•video resolution up to 1080p30 or 1080p60 (depending on the firmware loaded into the E412)
•video codec: H.264 (base, main and high profile)
•encoding chip: Geosemi Max64380 (http://www.geosemi.com/product/max64380/)
•only progressive video formats are supported (no interlaced video input)
•audio: PCM or compressed audio
•micro USB connector to connect to host system (with UVC driver)
•alternatively 2x2 2mm pin header to host system (on the bottom side)
•host system receives the compressed video stream and formats it with GStreamer or similar
•any protocol support through GStreamer (RTSP, RTMP, HLS, UDP or more)
•control of encoding parameters and firmware upgrade through MXCAM utility
•power consumption: 0.5 watt (with 1080p30 firmware) to 1 watt (with 1080p60 firmware)
•size: 22 x 64 mm
Host software
Auvidea provides the binary versions of the software below. Please find a list of host systems
supported in the list below. If your host system is not on the list, please contact us for the source
code of the software and its licensing details.
•optimised UVC driver for best performance
•MXCAM: control interface to the E412 module (including encoder firmware upgrade)
•QUERYDUMP: get detailed encoding parameters and statistics
Host systems
•x86 system with Ubuntu 14.04 LTS
•Raspberry Pi

Encoder Firmware
Release 4.3.27 (December 2016)
•support for audio (audio=external)
•8,16, 48 kHz audio sampling rate supported
Please let us know, if you do require other audio sample rates (such as 44.1kHz).
Firmware Images
The are 3 firmware images provided. fw-64380.img is the default image. The firmware may be
changed and/or upgraded with the MXCAM app. Please choose the default firmware unless you need
to support 1080p50 or 1080p60 encoding. Please note, that the other firmware sets a higher clock
frequency and doubles the power dissipation. This may require active cooling of the module.
Please use the QUERYDUMP app to monitor the clock frequencies set.
Below is a partial printout of QUERYDUMP with the default (200MHz) firmware image loaded.
$sudo querydump

UVC driver
Custom UVC driver
The E412 requires a custom UVC driver to be installed to get the best performance (frame rate).
Basic functionality is provided by the standard UVC driver, but the frame rate may be limited.
Below are the DMESG messages which shows the activation of the standard UVC driver.

HDMI input (J1)
Please connect an non HDCP video source with progressive timing. Interlaced video is not
supported. At startup the onboard micro controller inits the HDMI input chip and programs the
EDID. Once this has completed the HDP pin (19) is raised high, to flag to the HDMI source
connected, that the receiver is ready to receive a signal and that the EDID may now be read.
Micro USB 2.0 (J4)
This USB port puts out the H.264 encoded video stream and allows control and setup of the encoder
and the HDMI input chip via tunnelled I2C. As the USB port does not transfer any raw uncompressed
data but only compressed H.264 video data, the bandwidth of USB 2.0 (480Mbit/s max.) is more
than sufficient. J6 is an optional connector to bridge USB 2.0 from board to board.

UART2 (J5)
This UART2 port is the console interface to the on-board micro controllers. The commands are
described in a section below. Commands allow to setup the system and to retrieve the status like
the video properties of the HDMI video source connected. The baud rate settings of UART2 are
115200 8/N/1. Please use a USB to TTL UART converter. Swap RxD and TxD when connecting this
interface.
Encoder Debug UART (J3)
This optional UART port shows the debug and boot up messages of the Max64380 encoder chip.
Baud rate: 115200 8/N/1.
I2C port (J2)
This optional I2C port interconnects the Max64380, the on-board micro controller and the HDMI in
receiver chip. Normally the micro controller controls this bus as master. Please use the console
interface on UART2, to manually read and write registers of the HDMI receiver chip for debug
purposes. It is not recommended to use the MXCAM I2C tunnel to let the Max64380 take control of
this I2C bus, as this access could collide with the micro controller driving this bus.

Print the timing details for the HDMI video source connected. The example below shows the
1080p25 timing with an actual resolution of 1920x1080 an a total size of 2640x1125. 0 is
progressive. “528,148,44” is the horizontal timing (front porch, back porch, pulse width). “4,36,5”
is the vertical timing (front porch, back porch, pulse width)."
horizontal: 1920 + 528 + 148 + 44 = 2640"
vertical: 1080 + 4 + 36 + 5 = 1125"
“01” is the status.
