• FFMPEG - Concat 3 videos with one of the videos becoming a picture in picture overlay

  7 décembre 2022, par John

  I have been getting to grips with FFMPEG for the last few days...so please excuse my lack of knowledge. It's very much early days.

  


  I need to join 3 video elements together with one of the videos becoming an overlay at a specific time.

  


  intro.mp4

  


  mainvideo.mp4

  


  endboard.mp4

  


  I need the intro.mp4 to bolt on to the front of the mainvideo.mp4 and then ideally with 20 seconds to go before the end of the mainvideo.mp4, I need the endboard.mp4 video to be bolted on to the sequence and take over the frame. When this happens, I then need the mainvideo.mp4 to be overlayed in the top left corner and continue playing seamlessly through the transition.

  


  I also need the audio from the main video to play until the end of the video.

  


  I currently achieve this but putting all of the video elements into Premiere and exporting them out but I know this process can be much quicker with FFMPEG. For reference, here is an example of how it looks. If you skip to the end of the video below (just after 45 mins into the video) as the credits are rolling you will see the main video transition to the picture in picture overlay, and the endboard video take over the main frame.

  There will be lots of mainvideo.mp4 files that this will be applied to individually, and the lengths of these videos will always be different. I am hoping that there is a way to have the transition to the endboard.mp4 happen relative to 20secs before the end of the files. If not I guess I would have to manually input the time I want this change over transition to happen.

  


  I roughly understand in theory what needs to be done, but being so new to this world I am really unsure of how something this complicated would be pieced together.

  


  If there is anyone out there that can help me , it would be greatly appreciated !

  


  I have got my head around the process of merging videos together with a simple concat command and I can see that overlaying a video in the top left corner of the frame is also possible...but my brain cannot figure out the sequence of events that needs to happen to bolt the intro video on to the main video....and then have the main video transition into the picture in picture overlay video at a specific time, while also bolting on the endboard video for the main video to overlay onto.

  


  Any help for a complete newb would be so unbelievably appreciated !

• what protocol must use for broadcast live video ?

  19 août 2021, par user3807476

  A server is in the middle
And we want you to send live video to it

  


  And on the other hand, watch it through the HTTPS like https://server/live.pm4

  


  

  


  What protocols can be used for this purpose ?

  


  I used to do this experimentally with nodejs dgram and ffmpeg on the raw UDP and it worked fine !
but stability and security is an issue that must be observed !
