  It's My source
my module : yt-dlp

  


  It originally worked well.
How fix ?

  


• Setting HLS segment times

  16 février 2016, par James Townsend

  I am passing a processed video from openCV to ffmpeg via a pipe here is the code

  ./OpenCV & \
  
   tail -n +0 -f out.avi  | ffmpeg -i pipe:0  -hls_time 1 -hls_list_size 0 -hls_wrap 10 -hls_segment_filename '%03d.ts' stream.m3u8 

  My issue is the output .ts files are not in a uniformed duration they change from file to file.

  These are mostly long say 60 seconds. This means the connecting client has to wait for the first stream to finish before the playlist file (.m3u8) file is created. Therefor in this example they are 60 seconds or so behind live video and if the next .ts file is larger the streaming stops until this is finished. If the client tries to play before the next .ts file is created they are played the first .ts file.

  The frame rate from openCV is 1 frame per second.

  tail changes the output file of openCV called (out.avi) to a stdout.

  Any help would be great.

• Build a C++ project with OpenCV 4.5.x in Visual Studio with custom flags for ffmpeg

  18 mai 2022, par Ivy Growing

  Our C++ project in MS Visual Studio under Windows 10 uses OpenCV 4.5.

  


  #include <opencv2></opencv2>opencv.hpp>&#xA;#include <opencv2></opencv2>videoio.hpp>&#xA;#include <opencv2></opencv2>imgcodecs.hpp>&#xA;#include "opencv2/highgui/highgui.hpp"&#xA;#include "opencv2/core/core.hpp"&#xA;

  


  The project works well. The OpenCV uses ffmpeg as dependency for extracting video frames from a stream or a file. Our legals require following flags are not used when compiling the ffmpeg to approve the product release :

  


  

  • without --enable-gpl

  


  • without --enable-nonfree

  


  


  So far this page gets close to the answer, however, I cannot understand how to configure the Visual Studio to use custom flags just for ffmpeg and not for other dependencies. Elaboration is appreciated.

  


  The Visual Studio has challenging and pretty confusing (for me in person, often) menues and settings. This is the root of the question :

  


  How/where in Visual Studio can I see which flags are used for compiling of dependent libraries ?
Specifically, how can I check which flags are used in OpenCV to build the ffmpeg ?
