• Live streaming using FFMPEG via MPEG Dash

  4 février 2021, par mifol68042

  I have an application that creates gets frames for external source and creates a mp4 video every 60 seconds. I use OpenCV in Python to create an array of frames and then create a mp4 video every 60 seconds. Let's assume my file structure is like below :

  


  video_1.mp4
video_2.mp4
video_3.mp4


  


  Now I want this to be made into a live stream using FFMPEG via Apple HLS or MPEG Dash. I tried to run the following command to convert mp4 to hls :

  


  ffmpeg -i video_1.mp4 -codec: copy -start_number 0 -hls_time 10 -hls_list_size 0 -f hls test.m3u88


  


  I did a cat of the test.m3u88 file, I can see the following output :

  


  #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:50
#EXT-X-MEDIA-SEQUENCE:0
#EXTINF:50.000000,
test30.ts
#EXTINF:50.000000,
test31.ts
#EXTINF:25.000000,
test32.ts
#EXT-X-ENDLIST


  


  Next I did the same command for the video_2.mp4 but the contents of test.m3u88 is getting overwritten. I am not able to understand how to append to existing segments.

  


  My aim for this problem is that if I can append to the test.m3u88 file I can achieve live stream in my front end app. Is this the right way to get live stream or should I take another approach ? Please let me know examples if any that can help me on getting live stream to web app.

  


• Android live streaming [on hold]

  26 mai 2015, par Kelvin

  I’m currently on a project which is about to develop a android app to view surveillance camera’s live stream through internet. I know when the video stream transferred through internet will not be a 0 second delay live stream and the legacy could be high.

  The current structure of the system is : the traditional surveillance(cameras+NVR+storage ...) + broadcast server + app. The broadcast server will get streams from cameras\NVR\Storage. It supports RTSP\HTTP\RTMP.

  I googled it for two days, and I found some ways to do this.
  The first way is to use webview + js player. The second way is to use the video view and the Third way is to use FFMPEG or other libraries.

  My questions are :

  Can video view play live stream with url like "rtsp ://172.22.35.161:8554" ? All the tutorial I found is about play a video file using rtsp protocol.

  How’s the performance of using webview + js player (or Html5 player) ? Any suggested player I can use ?

  If using the FFMPEG or other libraries, is there any suggested library or tutorial ?

  Thanks for your patient of reading my question and thanks for you help in advance.

• Live Stream FFMpeg PHP [on hold]

  25 octobre 2016, par André Schmidt

  i’ve been search for this for about 4 or 5 days, with no success. I want to create a stream, where the client create a channel, like youtube, and when someone enter on channel, the video starts in the middle. EX :

  My streaming start on 15:00 and stop at 16:00. The viewer enter on channel on 15:30, and the video have to skip 30 minutes, as if it were live. How can i do this ?
