• Rtsp streaming with 3gp (Video encoded with ffmpeg) breaking every 8 seconds

  8 août 2012, par user1581063

  I have set up Darwin streaming server(6.0) to stream rtsp on android / other mobile devices in AWS using Ec2.
  I have opened all UDP and necessary tcp ports required for playing RTSP

  I am using ffmpeg to encode videos. Below is the command used for encoding a H264 video to H263.

  ffmpeg -i test1.mp4 -f 3gp -s 176x144 -vcodec h263 -b:v 339k -r 14.895 -acodec libamr_nb -ac 1 -ar 8000 -ab 12.2k -y test.3gp

  The encoded videos stops every multiples of 8 seconds, bufffers and plays again in all Android phone(< 4.0).

  I tried all the options still the behavior is same. The same RTSP link plays well with Daroon player( downloaded from google play) on Android or VLC player in windows.

  I am not able to figure whether its a encoding issue or server side issue.
