• 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

• ffmpeg : Combining two A/V streams results in out of sync audio in VLC play but not QuickTime [closed]

  24 juillet 2022, par Alex

  I have two files (one audio, one video, both mp4) I want to combine into a single mp4 without re-encoding the streams. They both have the same duration (well, technically one is 0.05s longer than the other, but it's close enough for my application). The command I am using to combine them is :

  


  ffmpeg -i audio.mp4 -i video.mp4 -c:v copy -c:a copy test.mp4

  


  When I play test.mp4 in VLC player, the audio is way out of sync. The video duration is correct, but the sound is all happening too soon and it gets more out of sync as it continues. However, if I play back the same file using QuickTime, it's perfect !

  


  What is going on here ? Is there a way for me to ensure correct playback regardless of video player, without re-encoding the streams ?

  


  Here's the full output of the command :

• ffmpeg - drawtext filter producing file with no streams

  24 juillet 2022, par yarrichar

  I am trying to get ffmpeg's drawtext filter working in an AWS lambda. Other operations like concatenating and trimming files works. But drawtext fails for some reason. I run the exact same command on my local machine and it runs fine.

  


  The output is below. The first line shows the parameters passed to ffmpeg.
You can see at the end of the following output that it's only processing 3 frames before exiting.

  


  Any help would be greatly appreciated.
