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.
