I am trying to get the metadata from a live .m3u8 stream and I was testing this using Mac and it is working and I can get the data I need, but when putting it onto a Linux (Debian) box, it omits the part that I need, the command is :

ffprobe -show_data http://livestreamurl.com

Which on Mac, outputs the data I need:

Input #0, hls, from 'http://livestreamurl.com':
  Duration: N/A, bitrate: N/A
  Program 0
    Metadata:
      variant_bitrate : 130000
  Stream #0:0: Audio: aac (LC), 48000 Hz, stereo, fltp
    Metadata:
      variant_bitrate : 130000
      title           : Crowded House - Locked Out

Specifically, it is the title part which is "Crowded House - Locked Out"

But when run on Linux, I get this:

Input #0, hls,applehttp, from 'http://livestreamurl.com':
  Duration: N/A, bitrate: N/A
  Program 0
    Metadata:
      variant_bitrate : 130000
    Stream #0:0: Audio: aac (LC), 48000 Hz, stereo, fltp
    Metadata:
      variant_bitrate : 130000

The Mac version is 4.4 and the Debian version is 3.2.16 (but says it is the latest version available), could this be the issue?

Is there a way for me to get what I need using the Linux box, which is the title section of the metadata on the audio stream?

Thanks.

Your AAC stream most likely has ID3 tags inserted between frames, which are only parsed starting with ffmpeg 4.x.

You can check the history of libavformat/aacdec.c.

The relevant commit is: Parse ID3 tags between ADTS frames.

Install or build a more recent version of ffmpeg on Linux.
