Record the installation and configuration of gestermer on TX2, and then use GST RTSP server

notes ： First of all, the construction process uses a piece made by the teacher himself tx2, The kernel has also been compiled , So I'm not sure if it can be applied to other places , In addition, because the kernel of this board has been compiled , Many unknown errors occurred during installation and use , It is possible that the recorded installation and configuration process will be omitted , If an error is reported somewhere at this time , Suggest Baidu check whether it can solve ;

First, enter... In the development board

gst-launch-1.0 --version

You can view the built-in of the current development board gst-launch and GStreamer Version of , Generally, the versions of various accessories installed should be less than or equal to the current version
Notice if it is 0.1 Version and 1.0 There are differences in the use of commands , Therefore, it is recommended to upgrade to 1.0 Version of
After checking the current version , I first installed the dependency libraries that I normally need , enter （ Here, because I referred to many posts in the early stage , I can't find the specific , Casually copied and pasted a copy , If there is any mistake or omission, please modify it in the line ）

sudo apt-get install build-essential dpkg-dev flex bison autotools-dev automake liborc-dev autopoint libtool gtk-doc-tools
sudo apt-get install libxv-dev libasound2-dev libtheora-dev libogg-dev libvorbis-dev
sudo apt-get install libbz2-dev libv4l-dev libvpx-dev libjack-jackd2-dev libsoup2.4-dev libpulse-dev
sudo apt-get install faad libfaad-dev libfaac-dev
sudo apt-get install libx264-dev libmad0-dev
sudo apt-get install yasm
sudo apt-get install libssl-dev

Then on this website https://gstreamer.freedesktop.org/src/ Download the supporting accessories in , My version is

gst-launch-1.0 version 1.8.1
GStreamer 1.8.3

So I downloaded , You can refer to

gst-libav-1.80
gst-plugins-0.8.12
gst-plugins-bad-1.8.3
gst-plugins-good-1.8.3
gst-plugins-base-1.8.3
gst-plugins-ugly-1.8.3
orc-0.4.23
gst-rtsp-server-1.8.1

Then unzip each attachment , Use

sudo ./configure
sudo ./autogen.sh
sudo make
suao make install

Statement to install , The installation sequence is generally from base–good–bad—ugly —lbav

If something goes wrong , There must be dependent accessories that are not installed
such as

sudo apt-get install gtk-doc-tools

If installing gst-rtsp-server-1.8.1 when , Special attention , In the use of

sudo ./configure
sudo ./autogen.sh

Observe whether there are statements like this output

configure: No package ‘gstreamer-plugins-base-1.0’ found configure:
error: no gstreamer-plugins-base-1.0 >= 1.8.0 (GStreamer Base Plugins)
found configure failed

You can try using the following statement to solve

sudo apt-get install libgstreamer-plugins-base1.0-dev libgstreamer-plugins-good1.0-dev libgstreamer-plugins-bad1.0-dev

Then reinstall good-bad Installation , On the way to gst-rtsp-server Run in the file

sudo ./configure
sudo ./autogen.sh

If you have the above tips , You can try

sudo apt-get install gstreamer-plugins-base-1.0
sudo apt-get install gstreamer-plugins-bad-1.0
sudo apt-get install gstreamer-plugins-good-1.0
sudo apt-get install gstreamer-plugins-ugly-1.0

Wait and see if it works

If all the above are installed , No problem
test udp Transmit to local for receiving display input

The sender

gst-launch-1.0 videotestsrc ! video/x-raw,format=I420 ! omxh264enc ! video/x-h264,stream-format=byte-stream ! rtph264pay mtu=1400 ! udpsink host=127.0.0.1 port=5000

The receiver

gst-launch-1.0 udpsrc port=5000 ! 'application/x-rtp,encoding-name=(string)H264' ! rtph264depay ! h264parse ! omxh264dec ! nvoverlaysink sync=false async=false 

test rtsp Transmit to local for receiving display input

The sender

./test-launch "(videotestsrc ! video/x-raw,format=I420,framerate= 25/1 ! x264enc ! video/x-h264,stream-format=byte-stream ! rtph264pay name=pay0 pt=96)"

The receiver

gst-launch-1.0 rtspsrc location=rtsp://127.0.01:8554/test ! rtph264depay ! h264parse ! omxh264dec ! nvoverlaysink sync=false async=false 

When inputting the codes of the transmitter and receiver , Or find a teacher to help solve , Because there is no number for the process of board encoding and decoding , Checking other people's codec process can't help you receive correctly

Enter... In the development board

gst-inspect-1.0 rtph264 

You can view some help documents

In addition, in the whole implementation process , If you can't write a program , You can also use wireshark The network debugging assistant monitors whether there is data transmission .
It can also be used. vlc Check whether the correct encoded image is transmitted , Baa, when there is correct transmission , stay vlc Of codec It will appear strange mp3 Format
