[SOLVED] kbps unknown flac (Lavf54.63.104)

Post by teodore » Sun Jun 17, 2018 5:00 pm

All the tools don't see the bitrate of some flac tracks coded with Lavf54.63.104.

they appear as stream radio (in foobar)!? No informations in MM, Mp3Tag, MuzicBrainz.

exemple with two different flac track of the same song:
  • Échantillonnage: 44100 Hz, Bitrate 854 kbps, 35.1 Mo
    Échantillonnage: 48000 Hz, Bitrate unknown, 43.2 Mo
Is there somebody who can give informations ?

These files do not contain info about sample count and duration (like live stream), that is why all tools including MediaMonkey do not display duration and bitrate. I would recommend to quickly reconvert them to FLAC in MediaMonkey with default settings (i.e. sample rate and bps set to "Default" in FLAC conversion settings). This operation will recreate the file header, and because the conversion to FLAC is lossless, you will not lose any audio quality.

Hi,
Just to clear things a bit more. The sample files you have sent to me are encoded/demuxed with LAV Filter and saved in FLAC format as Stream RIP that contain FLAC format Header (excluding sample count and duration) so in order to get that whole file needs to be analyzed or reconvert using DEFAULT settings in FLAC MMW encoder.

As MiPi already pointed and my Brute Force RAW Audio Data comparison confirmed, that both original and reconverted Audio Data are Bit Perfect.

As A result you just need to do Advanced MMW search using Criteria Extension equals FLAC, Track Length = 0 and Reconvert the listing Using all Defaults in Codec Options.
