• How to set start time of video saved from RTSP stream with FFMPEG

  12 janvier 2023, par hung

  I use FFMPEG to record video from a RTSP stream. What my code does is get current day time, create a folder with this format year/month/day/hour/minute and save the video to that folder.

  



  When a new minute arrive, I create the new folder base on the new minute and run the record again to the new folder.
Basically It works, but the next video start time is continue the end of previous video. For example :

  



  video1: 00:00 -> 00:55
video2: 00:56 -> ...


  



  I hope I can set for all videos start from 00:00. Can I do that ?

  



  Here my code

• FFMPEG Streaming Output Dropping On Virtual Server

  11 octobre 2017, par David Childers

  I am currently using FFMPEG to stream on a virtual CENTOS server. I use the following script to stream to youtube live.

  ffmpeg -re -i program.01.mp4 -flags +global_header -acodec libmp3lame -ac 1 -ar 44100 -ab 192k -s 1280x720 -vcodec libx264 -pix_fmt yuv420p -g 60 -vb 1700k -profile:v baseline -preset:v faster -r 30 -f flv "rtmp://a.rtmp.youtube.com/live2/xxxxx"

  I previously used the very same FFMPEG stream script to stream on a dedicated CENTOS server for over a year, with no technial issues.

  I tried to use the very same FFMPEG script on the virtualized server. When I use 1700k encoding speed - I get the following error in the output :

  [flv @ 0x56da380] Failed to update header with correct duration.
  [flv @ 0x56da380] Failed to update header with correct filesize.

  The youtube ingestor also complains that the input stream (coming from the CENTOS server) is slow and that the stream will buffer.

  I have checked the available output bandwidth that virtual CENTOS server has access to.

  • Download : 57.12 Mbit/s
  • Upload : 96.57 Mbit/s

  I am forced to use a much lower video encoding speed and output size

  ffmpeg -re -i program.01.mp4 -f-flags +global_header -acodec libmp3lame -ac 1 -ar 44100 -ab 128k -s 640x360 -vcodec libx264 -pix_fmt yuv420p -g 60 -vb 425k -profile:v baseline -preset:v faster -r 30 -f flv "rtmp://a.rtmp.youtube.com/live2/xxxxx"

  I am at a loss to understand what the problem could be since I have access to more than enough required bandwidth.
