• How to find audio stream with ffmpeg

  27 novembre 2019, par F O X

  how to find audio stream in ffmpeg if ffprobe showing smth like this :

  >Input #0, rtsp, from
  
  >'rtsp://192.168.1.15:554/live/ch00_2':   Metadata:
  
  >title           : streamed by the macro-video rtsp server   Duration: N/A, start: 0.967000, bitrate: N/A
  
  >Stream #0:0: Video: h264 (Main), yuv420p(tv, bt470bg, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 20 fps, 50 tbr, 90k tbn,
  
  > 40 tbc

  Already tried all channels but couldnt find it, is there a command that could scan all the possible channels to find the audio stream ?
  This camera has an audio output for sure, its working when im using their app. Is this possible that rtsp protocol doesnt have it ? or if it doesnt is there any other way that i could grab the audio stream into ffmpeg ?

• How to avoid critical security issues introduced by ffmpeg ? which seems to be a dependency of DeepFace for running opencv in linux environment

  29 août 2022, par Shubham Patel

  I was trying to run DeepFace in docker and when I ran the container I got an error related to OpenCV.

  


  Following online suggestions, I downloaded the FFmpeg package and it resolved the OpenCV error and everything was working fine inside the container.

  


  I ran a docker scan for checking the security issues and it highlighted 4 critical severity issues introduced through FFmpeg package

  


  Can anyone help me how to avoid these security issues ?

  


  Below is the content of the docker file :

  


  
RUN apt-get update
RUN apt-get install ffmpeg  -y

RUN pip install flask flask_cors deepface numpy pillow flask_wtf

WORKDIR /app
COPY . /app

EXPOSE 84
CMD ["python","app.py"]


  


  Below is the result of the docker scan which uses snyk, NOTE : I am just providing High and Critical Severity issues.
