• How to insert infinite audio into the live streaming by using ffmpeg ?

  20 juillet 2017, par Xiang Wang

  I use the following command to insert infinite audio into rtsp stream, but -stream_loop -1 didn’t work. How to fix it ?

  ffmpeg -i rtsp://admin:12345@192.168.31.104/h264/ch1/main/av_stream  -stream_loop -1 -i blank.aac  -vcodec libx264 -acodec aac -f flv rtmp://localhost/live/test

  This is the full console when I executed the following command :

• FFMPEG resizing ouputs 0B file

  26 octobre 2016, par Rahul Kumar

  I am trying to resize a .mp4 file to different resolutions.
  This is the command I’m using :

  /c E:\videos\manage\ffmpeg.exe -i "E:\media\SampleVideo1280x7201mb.mp4" -s 800x600 -ar 22050 "E:\media\encoded\med_SampleVideo1280x7201mb.mp4" 2>&1

  This works for most of the files but for some input files, the file that outputs is 0B in size and This is the message I get :
