• FFMPEG splitted video from rtmp stream having issue with audio

  9 avril 2021, par Shibin Raju Mathew

  Using ffmpeg, I'm able to split video from rtmp stream into different chunks, but having issue with audio. Each chunk having muted audio at the end. That means last few seconds of video is muted. Here I added the command what is used.

  


  ffmpeg -i rtmp://server-url -ss 00:00:00 -c copy -map 0 -segment_time 00:00:30 -f segment -reset_timestamps 1 %03d_split.mp4


  


  NB : if you can suggest any other library to do the same in java programs then it will be a great helpful. Thanks in advance.

  I am trying to convert all format videos to mp4 using libav library. I am using the following command to convert any format to mp4 i.e

  "avconv -i input -s 1024x768 -strict 2 -c:v libx264 -c:a copy -f mp4 output.mp4" and it is working fine in chrome and IE where as not working in Firefox and safari.

  You can find the issue here https://ppe.maventus.com/player.php?v=721

  Note : avi to mp4 is working in all browsers.

  Any help to fix this would be much appreciated.

  Thanks in advance,

• Extract the 0th frame of every second on a live video

  14 avril 2020, par geo-freak

  I have a command to extract the zero-th frame of every second. I got the command from here.

  



  ffmpeg -i input.ts -vf "select=between(mod(n\, 25)\, 0\, 0), setpts=N/24/TB" output-%04d.png


  



  But when I run the above command on live feed, it is extracting more than 100000 frames. The above command is not working on a live recording. Can anyone suggest or help me to extract the very first frame on a live recording ? Thanks in advance.

  



  P.S : For my testing I am running the above command on a tcr video.
