Introducation
The document describes the method of ZoBoVision E50I_Altera_C5 and
E50P_Altera_C5 H.265/HEVC encoder demo on Terasic SocKit FPGA board (Altera
CycloneV Series).
To execute the demo, please boot the linux from microSD card in SocKit board and
copy the execution file “zoboenc” and the source YUV file to Linux directory. Use Quartus
Programmer to configure FPGA with .sof or .jic file. Then, launch the ARM program
“./zoboenc” to copy the source YUV frames to be loop encoded from microSD card to
FPGA DDR3 memory, once the source frames ready on FPGA DDR3, the FPGA program
start to encoding process and wirte output bitstream to microSD card. Also the original
encode frames or reconstructed frames which is the same as the decoder output will
present on VGA port.

3.4 Copy YUV file to SD Linux
■For details about copying files to SD Linux directory, please refer to the document:
My_First_HPS.pdf
■In Altera SoC command shell, Copy the YUV file into the SD Linux folder
“/home/root”.
■Only standard YUV420 format file supported, such as the H.265/HEVC YUV test
sequence “BasketballDrill_832x480_50.yuv” and “BQMall_832x480_60.yuv”, etc.
■Only four kinds frame size supported for demo, as shown below:
1920 ×1080
1280 ×720
832 ×480
704 ×576

Zobo_Enc_Altera_C5_SocKit_Demo ZoBoVision H.265 Encoder Live Demo User Guide
www.zobovision.com 10
■The YUV file under the SD Linux folder “/home/root” should be named according to
the frame size , as shown below:
yuv420_1920_1080.yuv / yuv420_1920_1080_oth.yuv
yuv420_1280_720.yuv / yuv420_1280_720_oth.yuv
yuv420_832_480.yuv / yuv420_832_480_oth.yuv
yuv420_704_576.yuv / yuv420_704_576_oth.yuv
For example, if encoder frame size is set to 1920×1080，and the switch ‘H_SW0’ on
the fpga board is set to ‘0’, the file ‘yuv420_1920_1080.yuv’ will be used as the source
of the encoder. if ‘H_SW0’ set to ‘1’, ‘yuv420_1920_1080_oth.yuv’ will be used.
■Maximum number of the frames to be encoded is limited according to the frame size ,
as shown below:
1920 × 1080: 70 frames
1280 × 720: 180 frames
832 × 480: 440 frames
704 × 576: 420 frames
The frames beyond the max number limitation in the YUV file will be discard, and the
valid frames will be loop encoded frame by frame.
3.5 Start Demo
■Insert the microSD Card with the pre-built linux image into fpga board, and the
YUV420 file to be encoded and the executable file “zoboenc” should have been copied
into the SD Linux folder “/home/root”.
■Connect the USB cable to the USB Blaster II connector (J2) on the SocKit board and
host PC ( if necessary).

■If .SOF file used, download the .sof file into fpga borad. If .JIC file used and have
download into fpga board, skip this step.
■Open PuTTY.exe and click open button,Make sure the PuTTY configuration as follow:
57600 baud rate
no parity
1 stop bit
no flow control settings
■Press KEY6 (WARM_RST) on the SocKit board and after a successful boot, Type
‘root’ and press ‘Enter’ to login to the system, as shown below:

Zobo_Enc_Altera_C5_SocKit_Demo ZoBoVision H.265 Encoder Live Demo User Guide

■The encoder frame size should be set according to H_SW3 and H_SW2 on the
SocKit board, as shown below. And after the linux file ‘zoboenc’ executed, the frame size
should not be changed.
■The encoder YUV source file can be selected according to H_SW0 on the SocKit board,
as shown below. And after the linux file ‘zoboenc’ executed, The source file should not be
changed.

■The VGA display source can be selected by SW3 on SocKit board,as show below.
When SW3 move up, the loseless original frames wouled present on VGA port,
otherwise,the encoder reconstructed frames display. The display effect of the
reconstructed frames is equal to the decoder output of the encode bitstream.The VGA
display source can be changed anytime by SW3.
■The quant parameter of the encoder can be set by SW2/SW1/SW0 on SocKit
board,as shown below. And can be changed anytime.

■Execute the file by typing ‘./zoboenc‘ and press ‘Enter’, as shown below.
At the same time, The H_LED3 on SocKit board will turn off, if not, errors may occurs,
please check the steps ahead.
■Press H_KEY3 button on the SocKit board to start encoding process, as shown
below:
First, the source YUV frames to be encoded will copied from microSD card under
Linux folder “/home/root” to FPGA DDR3 memory, as shown below. This procedure may

Zobo_Enc_Altera_C5_SocKit_Demo ZoBoVision H.265 Encoder Live Demo User Guide
www.zobovision.com 16
take a few minutes. The total number of frames to be transferred is different according
to the encode frame size.
■When all the YUV frames to be encoded copied to FPGA DDR3 memory, FPGA
encoder start work, and LED0 on SocKit board start blinking. Meanwhile, original frames
or reconstructed frames will display on VGA monitor, and the encode bitstream write
back to microSD card under linux folder “/home/root” which named as “zobo265.bin”.
■The max sizes of the encoder bitstream write to SD card is limited to 128 Mbyte,also
you can press H_KEY0 on SocKit board to stop write bitstream ahead.
■Even if the encoder bitstream written is terminated, Encoder will keep working unitl
power down or press KEY6(WARM_RST) or KEY5 (HPS_RST).
■If a new encoding process is required, such as encode frame size or YUV file changed,
you should power down the SocKit board and repeat steps list above.
■In Altera SoC command shell, Copy the bitstream file ‘zobo265.bin’ from the SD
Linux folder “/home/root” to host PC, as shown below:

Zobo_Enc_Altera_C5_SocKit_Demo ZoBoVision H.265 Encoder Live Demo User Guide
www.zobovision.com 17
■On host PC, you can using media player such as VLC_media_player to play the
encoder bitstream ‘zoboenc.bin’, also you can using h.265/HEVC HM software to decode
‘zoboenc.bin’ and play the output YUV file by ‘yuvplayer’. When abnormal occurs with
media player, especially for 1080P bitstream decode, please using H265/HEVC software
to decoding the bitstream.
