Some snippets for gstreamer cookbook

• GStreamer cookbook

Environment

You can build a docker image by build-docker.sh and start it by start-docker.sh

or run the below command to intall gstreamer on ubuntu

sudo apt-get install -y gstreamer1.0-tools \
libgstreamer1.0-dev \
libglib2.0-dev \
gstreamer1.0-nice \
gstreamer1.0-plugins-bad \
gstreamer1.0-plugins-ugly \
gstreamer1.0-plugins-good \
libgstreamer-plugins-bad1.0-dev \
gstreamer1.0-plugins-base-apps \
libfmt-dev \
libspdlog-dev \
libyaml-cpp-dev
libgtest-dev

for MACOS, run similar commands by brew, but suggest downloading package from gstream site

brew install gstreamer
...
...
brew install googletest

for ubuntu, the google test library may not be found

sudo apt-get install libgtest-dev
cd /usr/src/gtest
sudo cmake .
sudo cmake --build . --target install

Example

• start SRS by docker

export CANDIDATE="192.168.0.106"
sudo docker run --rm --env CANDIDATE=$CANDIDATE \
  -p 1935:1935 -p 1975:8080 -p 1985:1985 -p 1995:8000/udp \
  registry.cn-hangzhou.aliyuncs.com/ossrs/srs:5 \
  objs/srs -c conf/rtmp2rtc.conf

• push local video stream from mp4 to rtmp

gst-launch-1.0 -vv filesrc location=material/talk.mp4 \
! decodebin \
! videoconvert ! identity drop-allocation=1 \
! x264enc tune=zerolatency ! flvmux streamable=true \
! rtmpsink location='rtmp://192.168.0.106:1935/live/waltertest'

• or run the C++ program

./build-with-vcpkg.sh
./bin/gst-pipeline-verify -f ./example/etc/pipeline.yaml -p pipeline_test_rtmp

• send/receive video stream over udp

# send video

gst-launch-1.0 -v v4l2src device=/dev/video1 ! decodebin \
  ! videoconvert ! omxh264enc ! video/x-h264,stream-format=byte-stream \
  ! rtph264pay ! udpsink host=192.168.104.236 port=5000

# receive video

gst-launch-1.0 -v udpsrc  port=5000 caps=application/x-rtp \
  ! rtph264depay ! avdec_h264 ! autovideosink

build source code

mkdir -p build
cd build
cmake ..
make

use vcpkg

• if you have not install vcpkg, please install it first

git clone https://github.com/Microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.sh
./vcpkg integrate install
./vcpkg install spdlog
./vcpkg install fmt
./vcpkg install yaml-cpp

• build with dependencies by vcpkg

./build-with-vcpkg.sh

use conan

• if you have not install conan, please install it first

python3 -m venv venv
source venv/bin/activate
pip install conan
conan profile detect --force

• create or update conanfile.txt for dependencies

• then run the following script to build

./build-with-conan.sh
