• Serving live video streams with Spring Boot ?

  29 octobre 2019, par ank

  Not sure if my question is correct/clear but basically I need help getting started building http video stream from different ffmpeg output with Spring Boot. I’m trying to build an NVR application. I plan to use ffmpeg to read ip camera streams (over LAN), produce an output and allow users to view these streams (live) through the web application (possible over the internet) or through http built using Spring Boot. I would also want to give users the ability to add more ip camera streams (within the web application) and have the application automatically run ffmpeg to read and write the output then make the live stream available for viewing within the application or through http.

  For the ffmpeg commands, I plan to use the ffmpeg-cli-wrapper library. For the live streaming from the application itself or through http, are there any libraries that I can use for this ?

• Bat file that extracts subtitle file then hard encodes the subtitle file into the original mkv file

  1er septembre 2019, par NolanWinsman

  My tv can play mkv files off of a flash drive but it cannot detect the subtitles files. I am trying to make a bat file that essentially takes the .srt file out of the mkv file then hard encodes it into the mkv file using ffmpeg. I am getting close but the naming is not working properly. For instance when it creates the subtitle file it names it infile.mkv.srt. When the file is encoded it is named infile.mkvEncoded.mkv. I am trying to get rid of the extra .mkv

  I am not great with variables in bat files so I am not exactly sure what to do. I added the "Encoded" part to the name of the file so that it doesn’t overwrite the original infile. I plan on just using bulk rename utility to get rid of that part unless there is a better way.

  My code is :

      DO (
  
      MKDIR Encoded_Files
  
      )
  
      FOR /F "tokens=*" %%G IN ('dir /b *.mkv') DO (
  
          ffmpeg -i "%%G" -vn -an -codec:s:0.1 srt "%%G.srt"
  
          ffmpeg -i "%%G" -vf "subtitles=%%G.srt" "%%GConverted"
  
          move *"%%~nG" "Encoded_Files"
  
              )

  The expected result would be infileEncoded.mkv*
