• android MediaPlayer alternative for rtsp streaming

  28 janvier 2014, par tulkas85

  I need to a multi viewer in my app, each view in a gridlayout must show a video from a camera that streaming over rtsp.

  I try using Android VideoView and MediaPlayer, but results does not satisfy me, I have much latency for starting video, and compatibility problems using Lg L9 phone (see my question here )

  I search a lot for 3rd party sdk , and I found Vitamio, but it not support multi-views in same activity (there is a bug). Another commercial sdk is Nexstreaming but not works on rtsp protocol.
  I not found nothing else. Do you know others ?

  Using NDK could be another way to do it, so I seen for Gstreamer (tutorial) but it seems too complicated. Another way could be FFMPEG, but I have not found a definitive guide for it.

  Any help ?

• php streaming video : can tmp file be accessed before move_uploaded_file ?

  5 août 2019, par Jintor

  My question is about accessing file while they are being uploaded to the server.

  Can I perform "live" video streaming but BEFORE move_uploaded_file ???

  because move_uploaded_file have to wait until the video is completely finished.

  <?php
  
  // Can I access tmp before move_uploaded_file ?
  
  move_uploaded_file('tmp_name','new_location');

  Is there a way to access the tmp file during upload and perform ffmpeg ?

  I was considering upload by chunk via xhr request... but it seems .mp4 from a mobile don’t necessarily apply a fast start...

  how live streaming services companies do it ?

  ---

  **** More clarifications :
  Live streaming. Example User X take his phone and want to go live, he hit a button "stream yourself" than the camera starts recording and while uploading, the server begins to save it to the server and other users like Y, Z, A, B begin to watch while X is still begin live

• dynamically update image in video stream using ffmpeg

  1er mars 2021, par omega1

  I have the following ffmpeg command which works, but I would like image3.jpg to update every 30 seconds (image3.jpg changes every 30 seconds). I read that I needed to move the file from a .tmp file image3.jpg.tmp to image3.jpg but this is not working either.

  


  The script places a few images on screen and takes an audio stream as its input and then outputs to a RMTP server, all works except image3.jpg only updates if I stop the ffmpeg command and restart it (which I cannot do as it is a live stream).

  


  I'm also struggling with where to add a drawtext within the filter_complex section if anyone could help with that also ?

  


  Thanks.
