  rtmpdh : Create sufficiently long private keys for gcrypt/nettle
  There was a misunderstanding betewen bits and bytes for the parameter
  
  value for generating random big numbers.

• nested loop in bash shell

  17 juin 2015, par Tareq Suheimat

  I want to stream video using ffserver and then receive and download it using ffmpeg but first I want to add some noise to the link using netem and the wanted noise will be Bit error,so for the transmitter side there’s no problem the problem is at the receiver side
  so the first loop must contain the percentage numbers of the bit error like 0.2 0.4 0.6 0.8 and do the following command :

  tc qdisc change dev eth0 root netem corrupt 0.1%

  then for each one of the bit error values must repeat it for 10 times and for each try I must download the received video using the following command :

  ffmpeg -i rtsp://localhost:7654/test1-rtsp.mpg -acodec copy -vcodec copy output.mp4 

  so later I end up with too many videos to compare them later.

  please people help me it’s urgent !!!

  tell now I have this scratched code but I don’t know how to compile it together

  for i in {0.2 0.4 0.6 0.8}
  
  do
  
      tc qdisc change dev eth0 root netem corrupt ${i}%
  
  
  
      #(must repeat for each i the ffmpeg download command 10 times)
  
  
  
      #The download command
  
      for x in {1..N}
  
      do
  
          ffmpeg -i rtsp://localhost:7654/test-rtsp.mpg -acodec copy -vcodec copy tested${x}.mp4
  
      done

  aacenc : coding style changes
  This commit only changes the coding style to a saner way
  
  of accessing coefficients (makes more sense to get the
  
  memory address of a coefficients and start from there
  
  rather than adding arbitrary numbers to offset a pointer).
  
  Some compilers might detect an out of bounds access easier.
  Also the way M/S and IS coefficients are calculated has been
  
  changed, but should still have the same result (with the exception
  
  that IS now applies from the normal coefficients rather than the
  
  pristine ones, this is needed for upcoming commits).
