• 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 !

  


• ffmpeg conversion x264 [error] : malloc of size 769152 failed

  18 décembre 2014, par prashanthp

  I am trying to convert video recorded from Android smart watch (.mp4 format) to a format (.mp4) which playable on all browsers. The video recorded from smart watch is not playing in the browsers. so, i’ve used ffmpeg to convert in into a playable mp4 format.

  But sometimes it is showing error as x264 [error]: malloc of size 503008 failed

  What is the reason for this. Sometimes it’s getting converted and sometimes it is showing error .

  Here is the console output.

• How to convert multiple 360 images to video

  9 août 2021, par Mashpy Rahman

  I need to convert multiple 360 images to video. Images will rotate from left to right. As like as this -
https://www.youtube.com/watch?v=99gXgkkFtA0

  


  I tried to do this using ffmpeg. but failed. Can you give me any idea or any website service link that I can make videos from 360 images.
