[Feature Request] inside Information tab show encoder info and replay gain if available

[Amaunator]

Could be useful to be able to see additional info in Information tab, such as tags: "Tool" (LAME3.97 for example) and "Track gain" : -7.65 dB...for example

It helps to see if album has been normalized and what encoder was used to create it. at the moment I need to fire up Foobar2000 in Wine to check that

QMPlay2 reads replaygain tags, so no problem for display. The "Tool" is not a tag and I don't know if FFmpeg can read it. Currently no plans for doing it manually.

http://gabriel.mp3-tech.org/mp3infotag.html they are tags apparently but there is a lot of "Jebanie się" involved to implement it without external library... if I'm not mistaken. plus: http://wiki.hydrogenaud.io/index.php?title=MP3#VBRI.2C_XING.2C_and_LAME_headers must be easier way to query.

in case of flac file one of the ways (my quick research shows) is to use metaflac library: "metaflac --list blahblablah.flac" that will spit out ` METADATA block #0 type: 0 (STREAMINFO) is last: false length: 34 minimum blocksize: 4096 samples maximum blocksize: 4096 samples minimum framesize: 14 bytes maximum framesize: 14265 bytes sample_rate: 44100 Hz channels: 2 bits-per-sample: 16 total samples: 97417488 MD5 signature: c861ddccea224a18e612e977860bf379 METADATA block #1 type: 3 (SEEKTABLE) is last: false length: 3978 seek points: 221 point 0: sample_number=0, stream_offset=0, frame_samples=4096

too much hassle & not worth the time in my opinion

mediainfo can show used encoder from FLAC files, but looks like it can't read it from MP3.

Doing it w/o external library probably is not so difficult (you gave me a specs), but there is a lot of different formats (FLAC, OGG Vorbis, MP3, etc.).

I'll check taglib soon - maybe it can read this...

For MP3 just open it in okteta and you'll see e.g. LAME3.93 somewhere in bitstream (begin and/or end of file). No need for Foobar via Wine 😄
