• Getting time codes in video files easier

  14 décembre 2024, par Arete

  I am going through some videos to trim them (extracting parts of the video).

  


  I know there is billions of software out there that can trim videos easily, but I haven't found any that does not recode the result.

  


  My method right now is to open the video in MPC-BE -> play -> pause -> note down the time -> resume to find a place end the clip -> pause -> note down the end time for the clip. Then I take the time codes and use ffmpeg to extract the part. Usually with something like :

  


  ffmpeg -i input.mp4 -ss 01:50:00 -to 01:55:00 -c:v copy -c:a copy output.mp4


  


  My question is is there an easier way to get the time codes ? The best thing would be to use ffplay to playback and just hit a key-combo to copy the time code. But I am also open any other approach that will make it easier to get the timecodes. As you probably understand, writing down the time codes manually for 23 clips is a real pain.

  


  Update : As of lately I have switched to TMPGEnc MPEG Smart Renderer 6 I found it easier to use than MPV. If any better alternative exist please let us know.

  


• Scalable Webinar Features Using Open-Source Tools ? [closed]

  31 janvier, par Firas Ben said

  I am searching for a scalable webinar solution that can handle 1000+ concurrent users. I have explored platforms like BigBlueButton but encountered limitations with scalability in real-world scenarios.

  


  My requirements include :

  


  

  • Support for RTMP and HLS streaming.

  


  • Chat and screen-sharing functionalities.

  


  • Ability to integrate with custom APIs.

  


  


  I’d like to know how to address these challenges using open-source tools. For instance :

  


  

  • What configurations are necessary to scale tools like BigBlueButton for large audiences ?

  


  • Are there specific architectural patterns or server setups recommended for handling this user load ?

  


  


  Any guidance or examples would be appreciated.

  


• Ffmpeg MP4 to HLS and Hosting

  22 février 2017, par Dave

  I am new to the world of FFmpeg. I’m currently transcoding my example.mp4 file to Hls with the following command.

  ffmpeg -i example_video.mp4 -hls_time 10 -hls_list_size 0 -strict -2 output_video.m3u8

  Once I execute this command the transcoding process starts and I get the a list of the following output :

  output_video.m3u8
  output_video0.ts
  output_video1.ts
  output_video2.ts
  output_video3.ts
  output_video4.ts

  I want to host this on my website so users can see the video.

  My question is, is the process of converting the mp4 to hls finished at this point ? Also how should I host this on my website, Should I bundle all these files in one directory and stream the video from the output_video.m3u8 file ?
