Hi,

I was wondering if foobar2000 supported gapless mp4 playback like it can do with LAME. I'm almost certain I remember reading it can, but I haven't had any luck. I'm using 0.7.6 with Case's nero encoder plugin to encode to .m4a from FLAC. I noticed that the file info box shows more samples for .m4as while FLAC, LAME, Ogg Vorbis, and MPC show the same lower number.
FLAC:

CODE

replaygain_track_peak = 0.99096680
replaygain_track_gain = -8.80 dB
replaygain_album_peak = 0.99389648
replaygain_album_gain = -10.58 dB
FLAC_vendor = reference libFLAC 1.1.0 20030126
bitrate = 1041
samplerate = 44100
channels = 2
bitspersample = 16
codec = FLAC
----------
7908600 samples @ 44100Hz

LAME:

CODE

enc_delay = 576
enc_padding = 1608
mp3_accurate_length = yes
bitrate = 128
codec = MP3
channels = 2
samplerate = 44100
mp3_stereo_mode = joint stereo
----------
7908600 samples @ 44100Hz

Nero 2.6.0.6:

CODE

codec = AAC
bitrate = 130
samplerate = 44100
channels = 2
aac_profile = LC AAC
tool = Nero AAC Codec 2.6.0.6
----------
7909624 samples @ 44100Hz

Both the LAME and Nero files were encoded from the FLAC file. Is there a problem with gapless mp4 playback or is it not supported?

Thanks

It does. The way info about encoder delay and original length is stored was changed some time ago to be less hacky and unfortunately there haven't been new Nero release since that. Next Nero version will use this new method and gapless mode will be working again.
PS. You can test the gapless mode already with FAAC, it was changed to use the new method immediately.

Nero 6.3.0.2 with AAC Codec 2.6.1.1 still uses old method

No it doesn't. It is properly gapless.

Edit: Sorry, it seems I was wrong. For unknown reason this version bundled old Aac.dll and gapless encoding is a no go. I didn't notice it as my newer version was kept in place.
