2 Run Flow



Please note that the Windows format option can't be used.

  • Copy all the files from the $TRD_HOME/images/<Path to Design Images>/ to FAT32 formatted SD card directory
  • Power on the board; make sure INIT_B, DONE and all power rail LEDs are lit green
  • After a successful boot, you may proceed with either GUI based application(Section 2.1) or command-line based GStreamer application(Section 2.2)

NOTE 1: The AR-69368 should be applied and rebuild the SD boot images for HighSD card.

NOTE 2: The SD card file system is mounted at /media/card. Optional storage medium SATA and USB are mounted at /media/sata and /media/usb respectively.

2.1 Graphic User Interface

A QT based graphical user interface (GUI) provides control and monitoring interface. GUI will run on DP only.

NOTE1: Qt GUI will work on for VCU TRD Multi-stream design and HDMI Video Capture and HDMI Display with the Audio design.

NOTE2: Make sure the monitor is in DP mode when you run the QT GUI app.

Run the below command to launch GUI on Display port when connected.

The GUI is not supported in HDMI Tx. In HDMI 4kp60 mode, GUI requires an additional ~2GB memory bandwidth. If you invoke the GUI cause memory bandwidth issue. So HDMI Tx, use only command line application (vcu_gst_app). The table below provides the supported display interfaces for both GUI and command-line applications.

Display InterfaceGUICommand Line Application
DisplayPort
HDMINot supported


The figure below shows the home screen of the GUI when only DP is connected.


GUI only supports single-stream playback. Supported resolutions are 1080p and 4kp. The supported frame rate for 1080p is 60 fps and 30fps for 4kp. For all multi-stream use cases and 4kp60 single stream, the user has to run command-line applications.

Qt GUI has the following options for the user to select:

Number of Input
This determines the number of active video sources. Only one input source is supported.

Output
This option allows the user to select a sink for the pipeline. Supported output sink types are display port, record, and stream. For the Display Port, the available Codec options are either enc-dec or Pass-through. For Record and Stream Out, the available Codec option is Enc.

Demo Mode

  • By clicking this button, the button text state changes to stop and the user can play all pipelines(TPG, MIPI, HDMI) with raw and presets configurations.
  • For every 10 seconds, playback preset changes and it plays in a loop till the user clicks on the stop button.
  • If no source connected it displays an error popup.
  • If any error returns in any playback, it skips and continues to play other pipelines.
  • With HDMI Video Capture and HDMI Display with Audio design, To enable audio in a demo mode goto→ Input Settings→ select Input1: HDMI→ Settings→ Audio Settings→ Enable Audio → true and Click on Demo Mode


Input Settings
The below figure shows the input settings window with configuration options.


Different configuration options available in the QT pop up window are:

Input Source (Input 1)
The following video sources (4K) are available as part of input video selection:

  • HDMI-Rx: To select the HDMI Rx source as input.
  • File: To select a file source as input.
  • Test Pattern Generator (TPG): To select TPG source as input.
  • MIPI: To select MIPI Camera source as input.
  • Stream-In: To select a streaming pipeline.


Codec
The following options are available as part of Codec functionality

  • Enc-Dec: This option is to select encode and decode in the pipeline.
  • Enc: This option is to select encode only in the pipeline for record or stream out a use case.
  • Pass-through: This option is to display raw video.


Preset
There are six predefined presets. If the user edits any control options preset mode switches to “Custom”.

  • AVC Low Encoder type = H264, bitrate = 10Mbps
  • AVC Medium Encoder type = H264, bitrate = 30Mbps
  • AVC High Encoder type = H264, bitrate = 60Mbps
  • HEVC Low Encoder type = H265, bitrate = 10Mbps
  • HEVC Medium Encoder type = H265, bitrate = 30Mbps
  • HEVC High Encoder type = H265, bitrate = 60Mbps

Profile = Main, Rate Control = CBR, Filler Data = true, QP = Auto, L2 Cache = true, Latency mode = Normal, Low Bandwidth = false, Gop Mode = Basic, B-frame = 0, Slice = 8 and GoP Length = 60 common for all above options.

  • Custom User-specific options

Please refer to the Supported Encoder Format section for the supported encoder format in this release.


SCD
Enable or Disable SCD in the pipeline


Settings
A user can control the encoder, record and stream out configuration from the GUI, Settings option is enabled when the pipeline is in the stop state. The user can control the encoder parameters when output option is selected as Display port/Record/Stream.


Encoder
This can be either H264 or H265.

Profile
The standard defines a set of capabilities, which are referred to as profiles, targeting specific classes of applications. These are declared as a profile code (profile_idc) and a set of constraints applied in the encoder. This allows a decoder to recognize the requirements to decode that specific stream.
H264 supports baseline, main and high profile. In H265 only the main profile is supported.

QP
Quantization in an encoder is controlled by a quantization parameter. It specifies how to generate the QP per coding unit (CU). Two modes are supported-

  • Uniform: All CUs of the slice using the same QP
  • Auto: VCU encoder changes the QP for each coding unit according to its content.


Rate Control
Constant bitrate (CBR), variable bitrate (VBR) and low-latency are supported. CBR mode generates a constant bit rate that you can predefine. CBR is recommended for limited bandwidth use cases.

Bitrate
Encoding bit rate. In digital multimedia, bit rate often refers to the number of bits used per unit of playback time to represent a continuous medium such as audio or video after source coding (data compression).

B-frame
Short for bi-directional frame, or bi-directional predictive frame, a video compression method used by the MPEG standard. It ranges from 0 to 4.

Slice
The number of slices produced for each frame. Each slice contains one or more complete macroblock/CTU row(s). Slices are distributed over the frame as regularly as possible. If slice-size is defined as well more slices may be produced to fit the slice-size requirement
Range:
4-22 4kp resolution with HEVC codec
4-32 4kp resolution with AVC codec
4-32 1080p resolution with HEVC codec
4-32 1080p resolution with AVC codec

GoP Length
In video coding, a group of pictures, or GOP structure, specifies the order in which intra and inter-frames are arranged. And GOP-length is a length between two Intra frames. The GOP is a collection of successive pictures within a coded video stream. Each coded video stream consists of successive GOPs, from which the visible frames are generated. Its range is from 1 to 1000.

Filler Data
Filler Data NAL units for CBR rate control to maintain constant bitrate throughout the playback. It can be enabled or disabled. It is applicable to CBR mode only.

L2 Cache
Enable or Disable L2Cache buffer in the encoding process.

Latency Mode
Encoder latency mode. It can be normal or sub_frame mode.

Low Bandwidth
If enabled, decrease the vertical search range used for P-frame motion estimation to reduce the bandwidth.

Gop Mode
Group of Pictures mode. It can be Basic, low_delay_p, or low_delay_b.

Record
When the Output option is selected as Record, A tab will be enabled in settings window through which a user can record the video into the storage medium.


Storage
This option specifies a storage device for the recorded file. The list is dynamically populated based on mounted storage devices. Supported storage devices are SD, USB, and SATA.

Output File Name
Name of the output file. For H264, recorded file get saved as <Source name>_H264_rec_<timestamp>.ts and for H265 it will be <Source name>_H265_rec_<timestamp>.ts

Duration
This option will specify the Recording time duration. It ranges from 1-3 mins.

NOTE: Due to speed and storage constraints it is recommended to use USB/SATA storage devices for the record.

Stream-out
The stream-out panel allows the user to configure streaming parameters.

Stream-out Prerequisites when zcu106 board is connected to host machine:

2.2 GStreamer Application (vcu_gst_app)

The vcu_gst_app is a command-line multi-threaded Linux application that uses the vcu_gst_lib interface similar to vcu_qt. The command-line application requires an input configuration file (input.cfg) to be provided in the plain text. Refer to the Appendix A - Input Configuration File (input.cfg) for the file format and description.

Before the execution of vcu_gst_app, we need to check the HDMI-Rx or SDI-Rx link status depending on the design. Refer to Appendix B for HDMI-Rx and SDI-Rx link status.

Before the execution of vcu_gst_app, we need to check the HDMI-Tx link and CRTC configurations depending on the design. Refer to Appendix B for the HDMI-Tx link up the issue.

Execution of the application is shown below:


Note: Required Storage medium SATA and USB are mounted at /media/sata and /media/usb respectively.

Example:

4kp60 HEVC_HIGH Display Pipeline execution

4kp60 HEVC_HIGH Record Pipeline execution

4kp60 HEVC_HIGH Stream-out Pipeline execution

4kp60 HEVC_HIGH Stream-in Pipeline execution

NOTE: Make sure HDMI-Rx should be configured to 4kp60 mode.

To measure the latency of the pipeline, run the below command. The latency data is huge, so dump it to a file.
