Summary: lame mp3 encoder does not save lame tags
Classification: Desktop
Product: GStreamer

As originally reported here:

It seems the gstreamer lame mp3 encoder isn't correctly saving the lame tags to
the files it creates. These tags are required in order to make the mp3s
gaplessly playback. For comparison, here's the tags from a gstreamer encoded
mp3 and one made using lame directly:
GSTREAMER:
$ eyeD3 --lametag 01.\ Café\ Tacvba\ -\ Seguir\ siendo.mp3
01. Café Tacvba - Seguir siendo.mp3 [ 4.02 MB ]
No LAME Tag
FROM LAME:
$eyeD3 --lametag Track01.mp3
Track01.mp3 [ 3.77 MB ]
Encoder Version : LAME3.98r
LAME Tag Revision : 0
VBR Method : Variable Bitrate method2 (mtrh)
Lowpass Filter : 18500
Radio Replay Gain : -2.0 dB (Set automatically)
Encoding Flags : --nspsytune --nssafejoint
ATH Type : 4
Bitrate (Minimum) : 192
Encoder Delay : 576 samples
Encoder Padding : 960 samples
Noise Shaping : 1
Stereo Mode : Joint
Unwise Settings : False
Sample Frequency : 44.1 kHz
MP3 Gain : 0 (+0.0 dB)
Preset : V2
Surround Info : None
Music Length : 3.77 MB
Music CRC-16 : 07F9
LAME Tag CRC-16 : E5BF
It's the encoder delay and padding tags which are especially important for
gapless playback, since this information is impossible to retrieve after
encoding.
