[jitsi-dev] voice recordig


#1

Hello, I use 1.1 jitsi.

- the names of file of recording definitely should contain called number.
- 128kbps mp3 has the same bitrate as PCMA -> not very useful compression.
- there should by "record by default" option (like in sflphone) - I every time forget to press record on important calls :slight_smile:

BTW
- the font of entered number is too tiny
- the info ([i] button) about call could be available even after hang up (before closing the call window).

But ... great program, thanks!

Hey kapetr,

Hello, I use 1.1 jitsi.

- the names of file of recording definitely should contain called number.

This would lead to unpredictable filenames (possibly exploitable by
malicious users) and it would also be tricky to handle for conf calls.

Of course users are free to choose any name they want when saving.

- 128kbps mp3 has the same bitrate as PCMA -> not very useful compression.

Bitrate is not the only means of compression used by MP3 and it does not
directly translate to disk usage. That's actually the whole point of
using it: getting a good quality for less storage space. Feel free to
compare a "wav" version of the recording to the mp3 one. From our
experience this the difference is between 3 and 10 fold.

- there should by "record by default" option (like in sflphone) - I every time forget to press record on important calls :slight_smile:

There is one. In the options windows:

Advanced->Call Recording, Check "Save calls to" and pick a location.

BTW
- the font of entered number is too tiny
- the info ([i] button) about call could be available even after hang up (before closing the call window).

The window should close automatically at most 5 seconds after the call
has ended and it also closes any related dialogs so this would be confusing.

But ... great program, thanks!

Thank you for your kind words!

Cheers,
Emil

Hello,

The format of the filename of the recorded call is changed to contain the
name of the remote party.

The change is included in revision 10442 in the svn and build
1.1.4467.10442.

Regards,
Hristo.

Hello Emil Ivov

> - the names of file of recording definitely should contain called number.

This would lead to unpredictable filenames (possibly exploitable by
malicious users) and it would also be tricky to handle for conf calls.

Of course users are free to choose any name they want when saving.

Any solution (e.g. only numbers - max 20 chars) would be better then nothing.
How to find call to/from e.g. my bank in many many files with call ?
And after every call to rename the file ...
Please try to thing about it.

> - 128kbps mp3 has the same bitrate as PCMA -> not very useful compression.

Bitrate is not the only means of compression used by MP3 and it does not
directly translate to disk usage.

Overall bit rate mode : Constant
Overall bit rate : 128 Kbps

so - every second == 16KB == it is "direct translate to disc usage".
G.711 = alaw = most used uncompressed codec = 8 kB ps. - this is not wav with 44.1kHz/16b but 8 kHz/8b

> - there should by "record by default" option (like in sflphone) - I every time forget to press record on important calls :slight_smile:

There is one. In the options windows:
Advanced->Call Recording, Check "Save calls to" and pick a location.

I have it set - but it does not record automatically. I have to press on every call
the record button. Jitsi 1.1

> BTW

this is in main window.

I agree adding a limited string would be helpful. Not sure at what point
we will be able to handle it but feel free to open a ticket.

Not necessarily after the call, uncheck the "save calls to" option and
you'll be asked to pick a file name before you start the recording.

Bitrate is not the only means of compression used by MP3 and it does not

Yes, this part looks right.

G.711 = alaw = most used uncompressed codec = 8 kB ps. - this is not wav with 44.1kHz/16b but 8 kHz/8b

This part isn't. We record 48KHz (or 44, depending on your devices and
codec). Your audio would always be full band, and the remote one would
depend on the codec.

- there should by "record by default" option (like in sflphone) - I every time forget to press record on important calls :slight_smile:

Oh sorry, I misunderstood. The thing you can set by default is store
location. You can't currently record all calls by default. Feel free to
open a feature request.

BTW
- the font of entered number is too tiny

this is in main window.

A screen shot would help.

Thanks,
Emil

Where can I do it, please?

> G.711 = alaw = most used uncompressed codec = 8 kB ps. - this is not wav with 44.1kHz/16b but 8 kHz/8b

This part isn't. We record 48KHz (or 44, depending on your devices and
codec). Your audio would always be full band, and the remote one would
depend on the codec.

What I mean is: if most used codec is alaw with 8kBps (8kHz/8b) then is not very useful to save it like 16kBps mp3 (44kHz/16b) - it just waste disc space.
Maybe would help more mp3 profiles to choose.
