errors in WAV header
--------------------
Key: LS-552
URL: http://dev.sourcefabric.org/browse/LS-552
Project: Liquidsoap
Issue Type: Bug
Components: Liquidsoap
Affects Versions: 1.0 beta
Environment: Liquidsoap 1.0.0-beta2+svn (@644dd3b27614:20110706:175811)
Reporter: peter
It seems that duration is not encoded in the right way when using reopen_when()
at 'output.file(%wav())'
test:
output.file( %wav(stereo=true,duration=3600.), "./test_%H:%M.wav",
reopen_when={0m0s}, mksafe(noise()) )
qwavheaderdump test_16:00.wav
test_16:00.wav (635054156 bytes):
riff: 'RIFF'
riff length: -268435457
riff length field should be 635054148
wave: 'WAVE'
fmt: 'fmt '
fmt length: 16
format: 1
channels: 2
sample rate: 44100
bytes/second: 176400
bytes/sample: 4
bits/sample: 16
data: 'data'
data length: -268435493
data length field should be 635054112
Romain has provided an additional parameter 'duration' (float) at %wav().
Using parameter 'duration' If record is sucessfully finished, length is encoded
in the right way.
qwavheaderdump test_18:00.wav
test_18:00.wav (635040044 bytes):
riff: 'RIFF'
riff length: 635040036

fmt length: 16
