To generate the .avi file, open a DOS command prompt from a Windows machine and run the
following convertor utility:
C:>raw2avi.exe vip_car_out.raw video.avi
You can view the video.avi file with a media player. The media player shows a grayscale version of the
source video file ( vip_car_0.avi ) that you can also play to see the full color video. You can view the full
sequence from which the clip is taken in the vip_car.avi file.
Video File Reader Test
The video file reader test is the simplest way of using the class library.
The video file reader test reads and translates the video file into
video_item
objects, streams to the DUT
using the BFM, and then retranslates video file back to video, and writes to the file again.
The test environment itself is set up through the
tb_test.v file (found in the example_video_files directory),
which instantiates the Qsys generated netlist, creates the necessary classes, and sets the test running.
The test has four main features of code.
tb_test.sv —first section of the code.
`timescale 1ns / 1ns
module tb_test;
`define CHANNELS_PER_PIXEL 3
`define BITS_PER_CHANNEL 8
import av_st_video_classes::*;
import av_st_video_file_io_class::*;
// Create clock and reset:
logic clk, reset;
initial
clk <= 1'b0;
always
#2.5 clk <= ~clk; //200 MHz
initial
begin
reset <= 1'b1;
#10 @(posedge clk) reset <= 1'b0;
end
// Instantiate "netlist" :
`define NETLIST netlist
tb `NETLIST (.reset(reset),.clk(clk));
// Create some useful objects from our defined classes :
c_av_st_video_data #(`BITS_PER_CHANNEL, `CHANNELS_PER_PIXEL)
video_data_pkt1;
c_av_st_video_control #(`BITS_PER_CHANNEL, `CHANNELS_PER_PIXEL)
video_control_pkt1;
c_av_st_video_user_packet #(`BITS_PER_CHANNEL, `CHANNELS_PER_PIXEL)
