Hi.

I’m trying to stream files to wowza with VLC without transcoding the file on the server.

i want to do this to safe the cpu.

i allready got it working with the video but there is no audio in it.

vlc -vvv /home/video/video.f4v --sout “#rtp{dst=127.0.0.1,sdp=file:///usr/local/WowzaMediaServerPro/content/test.sdp}”

The f4v file is created with FME. i streamed something to the server with it and recorded it as well.

Does anyone maby know what happend with the audio? or how to set VLC to only transcode the audio?

Gr

TH

See if this post helps. You may need to flatten the fragmented file:

The other problem could be that the audio is MP3. So you may want to look into the MainConcept AAC plugin for FMLE which will record the audio in AAC.

Hi Charlie

i allready fixed this problem.

It was like u told that the audio was mp3

vlc -I dummy /home/somplace/\*.f4v --random --loop --sout “#transcode{acodec=mp4a,ab=128,channels=2,samplerate=44100}:rtp{dst=127.0.0.1,sdp=file:///usr/local/WowzaMediaServerPro/content/test.sdp}” &

Thats the code i use now. perfect video and audio and only 10% cpu usage (better than 87% with video transcode).

Now i can finaly transcode the files at home and than upload.
