• Issue with ffprobe execution within Docker Environment

  7 mars 2024, par Khải Hồ Quang

  Here is my Dockerfile :

  


  FROM node:18-slim as builder

WORKDIR /usr/src/ai_api_builder/

COPY package*.json tsconfig.json /usr/src/ai_api_builder/

RUN apt-get update && \
    apt-get install mariadb-client -y && \
    npm install && npm cache clean --force

RUN apt install ffmpeg -y && \
    ffmpeg -version && \
    ffprobe -version
COPY ${REPO_DIR}/ ./

RUN npm run build && mv audio_store node_modules dist/

FROM node:18-slim

# Create and cd into app directory
WORKDIR /usr/src/dwt_api_app/dist

# Copy the artifact to the new image
COPY --from=builder /usr/src/dwt_api_builder/dist ./

EXPOSE 3001

ENTRYPOINT ["node", "app.js"]


  


  When I build Dockerfile, the step check ffmpeg and ffprobe version worked :

  


  ffmpeg version 5.1.4-0+deb12u1 Copyright (c) 2000-2023 the FFmpeg developers
built with gcc 12 (Debian 12.2.0-14)
...
ffprobe version 5.1.4-0+deb12u1 Copyright (c) 2007-2023 the FFmpeg developers


  


  But when I run container, my TypeScript code not work (the metadata return undefined) :

  


  import { ffprobe } from "fluent-ffmpeg";
ffprobe(latestFilePath, async function(err: any, metadata: any) {
    console.log("metadata", metadata);
})


  


  When I exec to container and check ffmpeg -version and ffprobe -version, I got : bash: ffmpeg: command not found. And when I check in bin folder, also couldn't find ffmpeg.
  
I tried it locally (Centos7), not in container, it worked (metadata return an object), and here is ffprobe version

  


  ffprobe version 6.1-static https://johnvansickle.com/ffmpeg/  Copyright (c) 2007-2023 the FFmpeg developers <b>&#xA;&#xA;</b>

  


  What step did I do wrong when running the container or is there any difference between debian (in container) and centos 7 (local) that I need to pay attention to ? Thanks

  


• How to resolve "runOnReady command exited with code 0" when restreaming a stream using Mediamtx ?

  2 juillet 2023, par Emad Helmi

  I'm attempting to publish a stream to the RTMP port 1935 using a ffmpeg command with Mediamtx (v0.22.2). Afterward, I want to restream the mainstream to another path using the runOnReady command in the config file. However, I'm encountering an issue where the runOnReady command exits with code 0.

  


  Steps to Replicate :

  


  

  1. Use the provided docker-compose.yml file :

  


  


  version: "3.8"

name: mediamtx
services:
  mediamtx:
    image: aler9/rtsp-simple-server:v0.22.2
    container_name: media_mtx_rtsp_server
    ports:
      - "8554:8554"
      - "1935:1935"
      - "8888:8888"
      - "8889:8889"
      - "9997:9997"
      - "8000:8000"
    volumes:
      - ./configs/mediamtx/config.yml:/mediamtx.yml
      - ../volumes/hls/segments:/hls/segments


  


  

  2. Add the following path to the config.yml file :

  


  


  paths:
  show/test:
    runOnReady: ffmpeg -i rtmp://localhost:1935/show/test -c copy -f flv "rtmp://localhost:1935/compressed/test"
    runOnReadyRestart: yes


  


  

  3. Start the server using docker-compose.

  


  4. Publish an RTMP stream to the server using the following command :

  


  


  ffmpeg -re -stream_loop -1 -i files/sample-30s.mp4 -c copy -f flv "rtmp://localhost:1935/show/test"


  


  

  5. When I check the logs :

  


  


  2023/07/01 15:16:30 INF [RTMP] [conn 172.26.0.1:51044] opened
2023/07/01 15:16:30 INF [path show/test] runOnReady command started
2023/07/01 15:16:30 INF [RTMP] [conn 172.26.0.1:51044] is publishing to path 'show/test', 2 tracks (H264, MPEG4-audio-gen)
2023/07/01 15:16:30 INF [path show/test] runOnReady command exited with code 0


  


  So I can't watch the stream on the new path (/compressed/test)

  


• Error setting option use_wallclock_as_timestamps to value 1 in FFmpegFrameGrabber - avformat_open_input() error -22

  29 mai 2023, par githubwyj

  avformat_open_input() error -22 Error setting option

  


  FFmpegFrameGrabber grabber = new FFmpegFrameGrabber("rtsp://xxxxx");
grabber.setOption("use_wallclock_as_timestamps", "1");
grabber.setOption("rtsp_transport", "tcp");
grabber.setOption("rtsp_flags", "prefer_tcp");

grabber.start();


  


  I used ffmpeg in JavaCV to pull rtsp streams, but there was an error like this

  


  Error: [rtsp @ 0x7f2770145a60] Invalid option type.

  When I removed grabber.setOption("use_wallclock_as_timestamps", "1");, the following error occurred：
