• Checking for files in a directory with bash script ? what is wrong with this code ?

  14 mars 2018, par A Sahra

  I have written this code to check for video files in a directory and convert them with ffmpeg.
  while running this script i get out put as "[ERROR] File Not Found" which i have it in else block.what is wrong with the script that i don’t get the files.

  #!/bin/bash
  
  # set PATH to check existance of video file in this directory
  
  checkfiles='/home/webuser/public_html/shareportal/convertedUp_videos/'
  
  #format of output video file
  
  webm='webm'
  
  for f in checkfiles
  
  do
  
  fullfilename="$f"
  
  filenamewithpath=$(basename "$fullfilename")
  
  filewithoutext="${filename%.*}"
  
  fileextention="${filename##*.}"
  
  changeextension=mv --"$f" "${f%.$fileextention}.$webm"
  
  outputfilename="/home/webuser/public_html/shareportal/converted_videos/$changeextension"
  
  echo "File FUll NAME : $fullfilename"
  
  echo "File name with full path : $filenamewithpath"
  
  echo "File name without extention : $filewithoutext"
  
  echo "File extention : $fileextention"
  
  echo '1 File Converted'
  
  if (ffmpeg -i "$f" "$outputfilename")
  
  then
  
  confullfilename="$outputfilename"
  
  confilenamewithpath=$(basename "$confullfilename")
  
  confilewithoutext="${filename%.*}"
  
  confileextention="${filename##*.}"
  
  echo "File FUll NAME : $confullfilename"
  
  echo "File name with full path : $confilenamewithpath"
  
  echo "File name without extention : $confilewithoutext"
  
  echo "File extention : $confileextention"
  
  echo '1 File Converted'
  
  else
  
  echo "Could Not Convert File"
  
  fi
  
  #get Image of video file on provided time stamp
  
  image_path='/home/webuser/public_html/shareportal/video_images/$filewithoutext.png'
  
  if (ffmpeg -ss 00:00:03 -i "$f" -vframes:v 1 "$image_path")

• Sample RTP code to stream x264 data

  5 août 2016, par Ajay Ponna Venkatesh

  I am using x264 library to encode frames and I need to stream it to a client which will receive the frame, decode and render it.
  Currently, I have borrowed the code from OBS to stream through RTMP and have written a client using FFMPEG’s RTMP code to receive this data. BUT RTMP works on TCP and I now need to stream over UDP. OBS doesn’t seem to support any other protocols than RTMP.

  So, I decided to use RTP. I can write a client to receive and decode using FFMPEG since it supports RTP just like RTMP. Can anyone please help me with sample code to stream x264 encoded data through plain RTP ? (I don’t want to complicate by using RTSP etc. along with RTP).

  The requirement is simple. Say, I use ffplay -> ffplay.exe rtp ://127.0.0.1:17000 then I want this sample code to be able to send data through RTP (over UDP) and ffplay should be able to play. I can take it over from there. Thanks in advance !
