  • Send data to udp port in azure virtual machine

    30 août 2013, par Anton Shakalo

    I use Wowza for live video streaming solution. I prefer to use windows azure as cloud hosting.

    For video streaming I need to open some udp ports.
    I have created endpoint for udp port 10000, map private and public ports to 10000 following instructions from here.

    I repeat this for http/80 port and it works fine.

    Then I tried to send video stream by ffmpeg with next command :

    ffmpeg -re -i "%WMSAPP_HOME%/content/sample.mp4"  -vcodec libx264  -vb 150000 -g 60 -vprofile baseline -level 2.1 -acodec aac -ab 64000 -ar 48000 -ac 2 -vbsf h264_mp4toannexb -strict experimental -f mpegts udp://%SERVER_IP%:10000?pkt_size=1316

    Where %SERVER_IP% is public IP address of my virtual machine.
    When I test locally, with 127.0.0.1 as server url, streaming works without problems.
    But now I can not see that video stream is coming to server.

    So I need help with this. How can I send data to udp port in azure virtual machine ?

    Also, I've tried to ping %SERVER_IP%:%PORT% by telnet and nmap but no success.
    If I describe something not clear on not correct - please comment and I will try to explain more detail.

  • Transcode to virtual device/memory in VLC

    27 septembre 2013, par Atrotygma

    I have a unicast h264 stream from a video transmitter. Now, I would like to view the stream in a web browser using HTML5s tag. For this, I have to transcode it first via VLC to theora/ogg and then streaming it out as a HTTP stream. This works fine for 1 client, but since HTTP streaming isn't multicast, I have the fear that my server will break down really quick because VLC will transcode the input stream for every additional client request.

    For this reason, I'd like to write the transcoded stream in something like a 'virtual device' or memory or any other form of temporary storage (but dear god, NO files, I don't want to destroy my hard disk). Then, I would like to grab the transcoded stream with a secondary VLC instance and stream it via HTTP, so that in the end, I have to transcode it only once for all clients.

    In steps :

    1. [DONE] Grab H.264 unicast stream from transmitter via RTSP
    2. VLC instance 1 transcodes it to theora/ogg and writes it to a temporary memory
    3. VLC instance 2 reads from the memory and streams it via HTTP
    4. [DONE] Browser requests HTTP stream via HTTP live Streaming (html5 video).

    Is this possible in any way ?
