• How do I enable ffmpeg python inside a docker ?

  4 mars 2024, par Noam Zadok

  I have a problem with enabling ffmpeg streaming inside my Docker container, and specifically, inside a Python service running inside the Docker.
I need to stream my screen view, and I'm using the 'x11grab' source, and the destination is an RTSP server (AWS IVS). This is my code for the stream :

  


  bit_rate = f"{self.config_service.thermal_stream_bit_rate}k" # 150k
vsync_param = self.config_service.stream_vsync_param # 'cfr'
frame_rate = self.config_service.stream_frame_rate # 5
stream_command = ffmpeg.input(
                os.getenv('DISPLAY'), # env var passed into the container
                s=f"{self.config_service.display_width}x{self.config_service.display_height}",
                f="x11grab",
                r=frame_rate,
                fflags="nobuffer+discardcorrupt+shortest",
                loglevel="level+debug",
            )..output(
                self.dest_path, # My rstp url
                vcodec='nvenc_h264',
                preset='hp',
                pix_fmt=pix_format_param,
                tune="zerolatency",
                b=bit_rate,
                g=keyframe_interval_seconds,
                r=frame_rate,
                format="flv",
            )
streaming_process = await stream_command.run_asyncio(pipe_stderr=True)


  


  When I run the code, I receive this error : x11grab: No such file or directory.

  


  When I enter the Docker container, and run Python, and then the script :

  


  import ffmpeg

>>> x11_display = ':0'
>>> format = "x11grab"
>>> screen_width = f"1920x1080"
>>> bit_rate = "150k"
>>> pix_format_param = "yuv420p"
>>> keyframe_interval_seconds = 2
>>> frame_rate = 5
>>> dest_path = 'rtmps://XXXX.global-contribute.live-video.net:443/app/YYYY'
>>> command = ffmpeg.input(x11_display, s=screen_width, f="x11grab", r=frame_rate, fflags="nobuffer+discardcorrupt+shortest", loglevel="level+debug",).output(dest_path, vcodec='nvenc_h264', preset='hp', pix_fmt=pix_format_param, tune="zerolatency", b=bit_rate, g=keyframe_interval_seconds, r=frame_rate, format="flv",)
>>> command.run()


  


  The stream is starting. I took the exact command by printing inside my service script (print the ffmpeg.input, and the ffmpeg.output).
Also, when I tried async running the command (as in my script) inside the Python console, it also succeeded, so it's not related to that. Basically there are no functional differences between the commands.
I've tried comparing the Python version, the ffmpeg version, the file system permissions - they are the same in the script run and in the python console.
I don't understand what configuration am I missing.
Thank you in advance.

  I have tried checking the directory in storage and check mkdir is working or not but this function purely works for creating video from a collection of images, themes, and audio. as per android
