  5 septembre 2013, par user2696962

  I want to choose the first audio stream. but for some reason, it's not working. it's always choosing the last audio stream

  what i've tried

  ffmpeg -i test.avi -vf "movie=watermark_720.png [watermark]; [in][watermark] overlay=main_w-overlay_w-10:10 [out]" -map 0:0 -map 0:1 -y -ar 44100 -ac 1 -vcodec libx264 -b 555K -threads 0 test.2.flv

  ffmpeg -i test.avi

• 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://..."
  
  ...

  Output #0
  
    Metadata:
  
      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.

  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 ?

• MPD doesnt load ffmpeg as decoder

  10 août 2022, par dmSherazi

  I am using openwrt 21.2.3 and mpd on it. I have compile mpd full and libffmpeg full as well as ffmpeg-full packages.
But my mpd wont load ffmpeg as decoder. Also tried to force it by adding decoder { plugin “ffmpeg” enabled “no” }” line to /etc/mpd.conf

  


  below is my mpd.conf

  


  log_file "syslog"

bind_to_address "127.0.0.1"
bind_to_address "192.168.1.16"

input {
    plugin          "curl"
}

audio_output {
    type            "alsa"
    name            "sun4icodec"
    device          "plug:dmix"
    mixer_control   "Power Amplifier"
}

decoder {
     plugin  "ffmpeg"
     enabled  "yes"
}


  


  the mpd —version output is as follows
