Hi,
I am currently trying to retrieve the length of the most recent recording, and I am using 'record_ms' channel variable.
However, the returned value is always '0'.

Here is the code I am using (lua):

...
session:recordFile(file, 30, 10, 10 );
local rlen  = session:getVariable("record_ms");  -- rlen is Always 0
...

Any ideas why?


Looking at switch_ivr_play_say.c, I found the line that sets this variable at the end of recording:

switch_channel_set_variable_printf(channel, "record_ms", "%d", fh->samples_in / read_impl.samples_per_second);
switch_channel_set_variable_printf(channel, "record_samples", "%d", fh->samples_in);

I also dumped the "record_samples" variable, which was also 0, so there are no surprises that record_ms was 0 too.
Please also compare the first function call to the analogous with "playback_ms"

if (read_impl.samples_per_second) switch_channel_set_variable_printf(channel, "playback_ms", "%d", fh->samples_out /   read_impl.samples_per_second);

The second one, checks for the "0" value in the denominator; the first one doesn't, so the potential segfault exists.


Cheers,
PV
