• Play MP4 while recording moov atom.

  2 septembre 2013, par Bavagnoli Paolo

  I am recording a video with VLC using MP4 Encapsulation + h264 codec. The video is recorded correctly , but I need to be able to access and play the recorded video while recording from a winform c# application.

  I have integrated VLC in the winform application but the problem is that the mp4 file is not playable during recording.

  I understood that the problem is the moov atom file is created at the end when the recording as terminated.

  First solution I have found is to copy the file when the user need to access the file then generate a moov atom using for example MP4Box utility.

  Does anybody know a better way to achieve this ?

  Thanks

• Split video stream with FFmpeg and play part with FFplay [closed]

  22 mars 2024, par Jan Hein

  I have a video stream send with FFmpeg to a other computer on my local network.
At the receiver computer I want to split the video stream in multiple parts and play them at the receiver computer. How can I do that ?

  


  Example :
Stream send form sender to receiver is 1000x1000 pixels.
At the receiver split the 1000x1000 pixel stream into four parts of 500x500 pixels, and play them all four on the receiver in a separate player.

  


  I have tryed it with a multicast stream to the receiver, and played it four times with FFplay, but that was not working correct.

  


  I also hve looked for multiple outputs with FFmpeg and then multiple pipes to FFplay, but could not find a solution.
