Looking at more details - 3h:22min relates to a WAV header size field
which has a width 32 bits.
Flac headers have a field size of 36 bits - so I'm guessing the original
problem occurred when encoding somehow with a WAV intermediary.
Use metaflac to confirm whether the file header is incorrect
e.g
Code:
--------------------
metaflac --show-total-samples testfile.flc
--------------------
or for full dump of STREAMINFO
Code:
--------------------
metaflac --list --block-type=STREAMINFO testfile.flc
--------------------
output will be something like
Code:
--------------------
METADATA block #0
type: 0 (STREAMINFO)
is last: false
length: 34
minimum blocksize: 4096 samples
maximum blocksize: 4096 samples
minimum framesize: 401 bytes
maximum framesize: 9336 bytes
sample_rate: 44100 Hz
channels: 2
bits-per-sample: 16
total samples: 8221416
--------------------
The following command re-writes the file header correctly without losing
metadata. I think it involves a decode and re-encode so may take time.
I tried variations of "-c:a copy" options to avoid decode/encode but
STREAMINFO was not rewritten.
Code:
--------------------
ffmpeg -i input.flc -f flac output.flc
--------------------
