  • Using ffmpeg with Flash Media Server and HDS

    20 avril 2012, par Jonathan

    I want to use ffmpeg to encode and publish a live stream to Flash Media Server. In order to support iOS devices, I need to implement HTTP Live Streaming as well. The video needs to be in H.264 format and the audio should be AAC. I don't have much experience working with ffmpeg, and I'm having a hard time getting this to work. This is the command that I've tried (and some variations as well) :

    ffmpeg.exe -threads 15 -f dshow -i video="USB2.0 UVC WebCam":audio="Microphone (Realtek High Defini" \
    
      -map_channel 0.1.1 -r 24 -acodec libvo_aacenc -ar 22050 -ab 128k -vcodec libx264 \
    
      -s vga -vb 100k -f flv "rtmp:///livepkgr/livestream1?adbe-live-event=liveevent" \
    
      -r 24 -acodec libvo_aacenc -ar 22050 -ab 128k -vcodec libx264 -s qvga -vb 200k \
    
      -f flv "rtmp:///livepkgr/livestream2?adbe-live-event=liveevent" \
    
      -r 24 -acodec libvo_aacenc -ar 22050 -ab 128k -vcodec libx264 -s vga -vb 350k 
    
      -f flv "rtmp:///livepkgr/livestream3?adbe-live-event=liveevent"

    When I run this, it appears to connect to FMS, but then I get a lot of error messages about dropped frames - I'm not sure if ANY frames get encoded successfully. My CPU usage is very high as well. I get a 404 error from FMS when I enter the URL of the *.m3u8 file for one of the individual streams (the main livestream.m3u8 file is accessible though). I have also tried outputting to a file instead of FMS, with no success. All I get is some very garbled sound and no video.

    Any suggestions for what options/commands I should use to get this working ? Is anyone using ffmpeg with FMS to do HTTP Dynamic Streaming / HLS with MP4 video ? I've been struggling to get HDS/HLS working for some time now, and any help would be much appreciated ! It shouldn't make a difference, but I'm using FMS on Amazon EC2 with their AMI image.

    Thanks !

  • Compiling FFMpeg libraries for Visual Studio

    20 janvier 2015, par LostBoy

    I’m trying to use the FFMpeg libraries in a Windows application. I use MingW-w64 to compile FFMpeg with static libraries with architecture once with x86 and once with x86_64.
    Currently I’m trying to link the 32bit x86 libraries with my VS2008 application.
    The libraries are added to the library path and VS does not complain about being unable to load a .a file.

    However I get several uneresolved symbol errors like
    ait_rtp_receiver.lib(ait_decoder_lib.obj) : error LNK2001 : unresolved external symbol _av_free

    I import the FFMpeg header files as extern C and I can see the symbols in the .a without the leading underscore.
    What can I do to make the name decoration of Mingw-w64’s gcc and of the VS compiler suite compatible ?
