  • How to convert audio for Asterisk .wav format


    In our example we take "sound.mp3" and convert it to .wav. Generally Asterisk for its wave needs one audio channel (-ac 1) / mono and 8000hz (-ar 8000) instead of the standard CD/MP3 of 44100hz. Here is the command to convert into Asterisk .wav format: ffmpeg -i sound.mp3 -ac 1 -ar 8000 sound.wav Errors Asterisk may give you if the format is wrong: -- Executing [91781891@cme:3] Playback("SIP/234-000........

    With ffmpeg it literally takes out what you want so you can use it later.

    This normally works but if not use my mencoder solution if the output video does not play past the joined time. the contents of list.txt need to look like this: file somefile.mp4 file somefile2.mp4 then run ffmpeg ffmpeg -f concat -i list.txt -c copy CME-2-router-dial-peer-final.mp4 The result is almost instant joining since there is no video processing since we are........
  • mencoder instead of ffmpeg to join or concatenate video files with different audio streams


    The problem for me is that Ihad two videos with different types of audio streams. ffmpeg would join them but they would not play past the point of the join. So Iused mencoder like below and it joined the audio and made them both mp3 streams and it worked! -oac mp3lame specifies the audio to be convered into an mp3 stream using the lame codec. after the oac the two files are the ones to be joined. the -o is the name of the outp........
  • How To Setup a Cisco CME (Cisco Manager Express) Virtual Router under Linux using dynamips and dynagen


    This tutorial will get your router up and running using emulation tools. In this case we'll be getting a Cisco C7206 (C7200 series) VXR router going which also supports SCCP VOIP services. dynamips is the emulator itself and dynagen is the front-end tool that helps us control everything. It is used by tools such as gns3 and eve-ng. Together the two tools (dynamips and dynagen) allow us to create and emulate REAL router........
