• Download RTSP recording content between two dates and times, or from start seconds to end seconds

  23 septembre 2022, par holt2

  I need to download from an RTSP link the content recorded on an IP camera from a start and end date and time. It would also be valid to be able to download it from X seconds of start of the recording to seconds of end.

  


  With this ffmpeg command I download the recording content from the RTSP link only from the beginning of the recording content, with the duration in seconds passed by the -t parameter :

  


  ffmpeg -rtsp_transport tcp -i  -r 30 -t <seconds> -y -vf scale=800:-1 -c:v libx264 -crf 20 -preset fast -c:a aac -strict experimental -b:a 192k -ac 2 /path/to/video/filename.mp4&#xA;</seconds>

  


  I tried to download with ffmpeg the content using temporary media fragment URIs (https://www.w3.org/2008/WebVideo/Fragments/wiki/UA_Server_RTSP_Communication#.281.29_Temporal_Media_Fragment_URIs) but it doesn't do it correctly :

  


  ffmpeg -rtsp_transport tcp -i #t=10,20 -r 30 -y -vf scale=800:-1 -c:v libx264 -crf 20 -preset fast -c:a aac -strict experimental -b:a 192k -ac 2 -ss 19:09:13 -t 5 /path/to/video/filename.mp4


  


  I have also tried with ffmpeg to use the -ss parameter to try to extract the recording from a specific hour, minute and second (https://trac.ffmpeg.org/wiki/Seeking) but when running it gets stuck, it does not advance :

  


  ffmpeg -rtsp_transport tcp -i  -r 30 -y -vf scale=800:-1 -c:v libx264 -crf 20 -preset fast -c:a aac -strict experimental -b:a 192k -ac 2 -ss 19:09:13 -t <seconds> /path/to/video/filename.mp4&#xA;</seconds>

  


  In case it's helpful, to get the RTSP link, I'm using the ONVIF protocol with a NodeJS library (https://github.com/agsh/onvif). I have also reviewed the ONVIF documentation available but have not found a way to download recorded content between start and end dates and times.

  


  Do you know how to download from an RTSP link the content recorded on an IP camera from a start date and time and end date, or download it from X seconds of recording start to seconds of end ?

  


  I am also open to use other tools or commands that can do this.

• 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
