• iPAD Streaming video to a ffmpeg server. front facing camera

  6 December 2011, by IrishGringo

  This is a video chat type program.
  My project is to write a native ObjC app that will stream video from the front facing camera to a server. This server will format and relay to be sent to another location.
  In a related question, I want to display video streaming from the server. The video server will probably be running ffmpeg for formating.
  But this question is just asking advice for the iPAD project. I wanted to get comments about issues I need to be thinking about.

  This is my strategy:
  I was thinking of using AVFoundation framework to stream from the cam to a URL server. I don't know if I will be formatting on the client or no, so some comment there would be interesting. http://developer.apple.com/library/mac/#documentation/AVFoundation/Reference/AVFoundationFramework/_index.html

  For streaming the video, I was going to be using:
  http://developer.apple.com/library/IOs/#documentation/AVFoundation/Reference/AVCaptureSession_Class/Reference/Reference.html#//apple_ref/occ/cl/AVCaptureSession

  so if someone has some ideas/suggestions... extra code I can look at. I would appreciate it.

• Video Surveliance application by connecting DVR

  14 May 2014, by iMOBDEV

  I am trying to connect to the DVR so that I can view video recording on my IOS device, I tried to search a lot but could not find a single useful link to move ahead with connecting to the DVR. I found that, it can be done using FFMPEG, but could not be able to do what to do and how to do.

  What I need to do is: connect to the IP address and port where the DVR is configured, give username and password for that DVR to connect to the DVR. Something like following link:

  Guide me with useful links to move ahead with connecting to the DVR.

• FFmpeg RTSP Recording: Video Timestamp Does not Match With Recorded MP4 File Timestamp [closed]

  26 April 2024, by lastpeony4

  I'm currently testing by streaming a 30 fps example flv video using a local Happy-Time RTSP server.

  


  This is the flv file i am streaming with RTSP:

  


  

  


  I recorded the video with below ffmpeg command:

  


  ffmpeg -i rtsp://127.0.0.1:6555/test30fps.flv -c copy test30fps.mp4


  


  The resulting video appears visually satisfactory, yet there's a discrepancy between the displayed time on the video and the actual duration of the video file. Although the MP4 file duration is correct (endRecordingTimeMs-startRecordingTimeMs= mp4 file duration), the time displayed within the video does not synchronize precisely with the file's time. Notably, this disparity escalates as the video progresses.

  


  I anticipate the time text overlaid on the video and the file's time to align seamlessly. However, a few seconds of divergence are noticeable, gradually expanding over the video's duration.

  


  

  


  Why does this occur and is there any way to fix this?
