  ffserver : add comment about how Launch path program is created
  

  • [DH] ffserver.c

• HLS files(.m3u8, .ts) does not created on nginx_rtmp_module

  6 mars 2018, par sujoyu

  I want to treanscode RTSP to RTMP to HLS using ffmpeg and nginx_rtmp_module.

  But HLS files(.m3u8, .ts) do not created.

  I’m testing on Docker(amazonlinux image).

  I can access and play rtmp://localhost:1935/live/camera1 by VLC Player, but can not access http://localhost:8088/live/camera1.m3u8.

  docker run command :

  docker run -it -p 8088:8088 -p 1935:1935 -v $(pwd):/tmp/share amazonlinux bash

  nginx.conf :

  user root;
  
  worker_processes  1;

  }
  
  
  
  rtmp {
  
    server {
  
      listen 1935;
  
      access_log  /var/log/nginx/rtmp_access.log;
  
      application live {

        hls_fragment 5s;
  
        hls_type live;
  
        hls_nested on;
  
      }
  
    }
  
  }
  
  
  
  http {
  
    server {
  
      listen      8088;
  
  
  
      location / {

• Extracting frames from a video created by muxing a bunch of images together is changing the integrity of the frames [closed]

  13 mars 2023, par dreamersparadox

  I am trying to transfer a bunch of images as a video. What I am doing is simply muxing these static images into a video using the following commands.

  



  ffmpeg -framerate 1 -i %02d.jpg -codec copy 1.mkv


  



  After this, I verify the integrity of my static images and the frames in the video using -

  



  ffmpeg -i %02d.jpg -f framehash -


  



  and

  



  ffmpeg -i 1.mkv -map 0:v -f framehash -


  



  I get the same hashes so it means I have archived the images properly. Now next I send this video to my friend who extracts the frames using -

  



  ffmpeg -i 1.mkv mkv%02d.jpg 


  



  Now after extracting the hashes don't remain the same that means the integrity is lost.

  



  How to extract the frames as it is so that integrity is not lost ?

  



  Also if you any other way to achieve what I am trying, please advice.

  



  Here are the hashes.
