show rtsp stream in streamlit web via ffmpeg, You can set the hardware acceleration manually set it in the code.
1. Dependent Environment
sudo apt install ffmpeg
pip3 install streamlit opencv-python
2. Change ffmpeg Configuration
To change the FFmpeg settings in st_rtsp_main.py, modify lines 20-30 as follows:
If you do not have the relevant hardware or install the relevant drivers, do not modify it.
for intel vaapi(You need to install the relevant drivers yourself)
process = subprocess.Popen( [ ‘ffmpeg’, ‘-hwaccel’, ‘vaapi’, ‘-vaapi_device’, ‘/dev/dri/renderD128’, ‘-i’, self.stream.rtsp_url, ‘-f’, ‘rawvideo’, ‘-pix_fmt’, ‘bgr24’, ‘-’ ], stdout=subprocess.PIPE, stderr=subprocess.PIPE )
for nvidia h264(You need to install the relevant drivers yourself)
process = subprocess.Popen( [ ‘ffmpeg’, ‘-hwaccel’, ‘cuda’, ‘-hwaccel_device’, ‘0’, # Use the first GPU ‘-i’, self.stream.rtsp_url, ‘-c:v’, ‘h264_nvenc’, # Use NVIDIA’s H.264 encoder ‘-f’, ‘rawvideo’, ‘-pix_fmt’, ‘bgr24’, ‘-’ ], stdout=subprocess.PIPE, stderr=subprocess.PIPE )
3. Run Test
streamlit run test.py
