  • FFmpeg streaming to Akamai like FMLE does

    21 juin 2013, par xdev.developer

    I am trying to stream video from my webcam to AkamaiHD service using ffmpeg (like it is implemented in Flash Media Live Encoder)

        ffmpeg -f dshow -i video="Webcam C110" -s 640x360 -aspect 16:9 -profile:v baseline -    pix_fmt yuv420p -vcodec libx264 -f flv "rtmp://..."
    
...
    
   Input #0, dshow, from 'video=Webcam C110':
    
  Duration: N/A, start: 31296.194000, bitrate: N/A
    
    Stream #0:0: Video: rawvideo (YUY2 / 0x32595559), yuyv422, 640x480, 30 tbr, 10000k tbn, 30 tbc

    encoder         : Lavf55.8.102
    
    Stream #0:0: Video: h264 (libx264) ([7][0][0][0] / 0x0007), yuv420p, 640x360 [SAR 1:1 DAR 16:9], q=-1--1, 1k tbn, 30 tbc
    
Stream mapping:
    
  Stream #0:0 -> #0:0 (rawvideo -> libx264)
    
....

    The video is sreamed, but when I try to view it at http://mediapm.edgesuite.net/edgeflash/public/zeri/debug/Main.html?url=myplayback_url/manifest.f4m
    it is not displayed.

    I've found out that if the video is recorded using FMLE and restreamed to akamai, then HLS stream is played.

    ffmpeg -re -i sample.f4v -c copy -f flv "rtmp://..."

    It seems that the problem is with h.264 codec configuration, but I have found no solution yet.

    Could you please advice, how can I implement streaming like FMLE using ffmpeg ?
