[MPlayer-users] M player for linux will support lossless format mp3HD?

[Frater AEC]

Carl Eugen,

  I generated the 2 samples 128 legacy mp3 and 128 and lossless mp3HD:

Encoding file: 01 - desconhecido 1 - Faixa 1.wav =>
sample-128-and-lossless-mp3HD.mp3

Duration:  3:39:280
mp3 Bit Rate: 128 kbit/s
mp3 VBR mode: 0
Channels: 2
Sample Rate: 44.1 kHz
Stereo Mode: 1
Fat entries: 100 (mp3 100)
Coded Frame:  8397 Time:  3:39:280

and

Using polyphase lowpass filter, transition band: 18671 Hz - 19205 Hz
Encoding 01 - desconhecido 1 - Faixa 1.wav to sample-legacy-128.mp3
Encoding as 44.1 kHz j-stereo MPEG-1 Layer III VBR(q=2)

I can send samples for your personal email in order to open the
request for FFmpeg enhancement?

True.

Please provide mp3hd samples, two files are needed,
one with the mp3hd content and one that contains
identical data encoded with a supported format.

Please do not top-post here, Carl Eugen
