Alternate Codec Support #49

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
If possible, it would be REALLY helpful if multiple codec support was
included as there are a couple codecs that would be much better for a phone
like this. Or even set a fallback codec, however that is not even close to
mattering...

The codecs that would be EPIC to see supported are:

ILBC - Internet Low Bitrate Codec (Good for edge, or low signal)
GSM  
G729
G711

Thanks!

actually I can confirm that since the last SIPdroid release (1.4.6 beta) the 
g722 
codec is working fine both ways.

achtubcvt, I would recommend you configure your router for NAT-PMP or UPnP 
instead of 
having to forward ports. This might resolve your audio problem. Have a look at 
this 
page: http://wiki.freeswitch.org/wiki/Auto_NAT

We also might want to move this discussion to the FreeSWITCH mailing list or 
irc 
channel if need be.

Are the codec source code compiled using NDK available for download? If they 
are,
where can I find them? Thanks.

I was really hoping sipdroid had support for iLBC codec. I can see the latest 
version
(1.4.7 beta) has support for a number of codecs, however most of them can't be 
used
by google voice + gizmo5 combination, or gv+g5+pbxes either.

Since now other codecs are being used, and iLBC is royalty free, is it possible 
to
implement it on sipdroid? Or is there some other limiting factor on Android?

Is it possible to enable Speex Wideband and BV32 codecs also or the processor 
cannot handle the extra load?

Lack of g729 support in Sipdroid is a showstopper for me.

freephoneline.ca only supports the g729 codec.

Outgoing calls only get silence, incoming calls fail with "ERROR: Codecs 
Incompatible' message.

Please this is a needed codec.

Csipsimple and linphone now both support ILBC.  Csipsimple also sounds really 
good and supports multiple simultaneous accounts.  Sipdroid needs to start 
releasing updates.

I have a very good experience with the AMR codec that is officially supported 
by Android
http://developer.android.com/guide/appendix/media-formats.html
The experience comes from some nokia devices like (N95, E61...). There are some 
SIP providers (like Truphone) that do have amr support, note also that asterisk 
PBX can be patched to include amr codec. 
This codec works very well even over slower internet connection and probably 
can be easier to implement than some other codecs options mentioned above.

Hi,

We want to integrate a wideband codec(16kHz sampling rate) with Sipdroid (Using 
NDK and JNI). 

We have tested the Sipdroid on the Emulator and using Asterisk Server. The 
Sipdroid works well (emulator environment) for alaw, ulaw, gsm and Speex. For 
G722 , though it is supported in Asterisk Sipdroid does not work.

Does Sipdroid in Emulator have any restriction on the Sampling rate? (i.e only 
8000 Hz sampling is supported ? ) This we want to know since we are trying to 
integrate a Wideband codec with Sipdroid. If there is restriction with 
Emulator, does on a hardware,Sipdroid work with any sampling rate?

Also since the codec which we are working on is not implemented on Asterisk 
server, will the channel be setup (atleast passthru)? Is there any way we can 
add new codecs to the Asterisk server

Any guidance in these issue is appreciated.

I feel like the developers still dont understand the significance of what we 
are asking:
1) focus on implementing Addon system which allows delegating the codecs issue 
to a third party.

2) Add "profiles" please - so I can uninstall, reinstall, swap between 
different SIP accounts without having to redefine everything, and easily backup 
the settings file from the SDcard.

I will say again, number 1 is very important mostly due to G729 codec - not 
only its the wide SIP standard by literally every SIP provider I checked, but 
it enables COMPRESSION! the PCMA and PCMU are constant, 64kbit rates which will 
require me to upgrade to unlimited data plan - and suddenly SIP and VoIP is not 
so cheap...

Thanks every one.At last i complete g729 codec for android sipdroid open source 
project.G729 codec development for sipdroid is possible.Thanks every one of 
android developer those people who help me to complete the sipdialer.i think i 
will get help from this forum later if i face any problem.last time i talk with 
from my HTC Wildfire device about 1 hour successful call.voice quality with 
g729 codec was very good for me.if any one face "can't hear the other person" 
problem then you just install the apk for your device (HTC wildfire) and after 
installed your sipdroid application just reboot your device i think problem 
will be solve.

Without ARM optimization the G.729 implementation from ITU is unusable on 
embedded devices.
Off course, it will work on a 1GHz device but it will use at least 40% of the 
CPU which means that you won't be able to add any other stream to the session 
(e.g. Video).

To convert the ITU bitstream from/to RTP as per RFC 3551:

GoogleCodeExporter commented 9 years ago 
we dont care if its 40% or 50%.
We want it working even without the video :)
Though I think remaining 50% should be enough to power not overly compressed 
video.
Anyway who walks around with video calls? video calls are normally done at home 
or office on laptop, not when you are mobile.

If someone has a g729 working on the 1ghz snapdragon, I'll take it anyday as I 
am sure will 90% of the others here.
The rest can keep sucking with their older phones :)

@carmageddon

1. 40%-50% CPU usage means aggressive battery usage which means shorter life. I 
guess you don't want to change your phone each year because the battery is dead?

2. 40-50% for audio (even without video) means that the phone only have 50% of 
the CPU resources to run. Try to read your mails, fetch your contacts, .... and 
you will understand what I mean.

@boss:

1. Again I dont care - I will buy a new battery, it needs to be replaced anyway 
after 1-2 years. Why would I replace the whole phone? I am not iPhone user lol.

2. Again I dont care - while I am on a phone conversation, lol I cant speak and 
use the phone at the same time.. sure there is Bluetooth etc. But you forget, 
nobody forces you to use g729. who doesnt like the cpu costs, could set another 
codec.

if we use default frame size that was 160 then session destroy after 2

if frame size is 240 then session established and one sided voice is ok.

my testing program shows that iLBC on emulator does not work. It is too slow. 
Encoding 30ms PCM to iLBC30 packet needs  about 100ms. I am not sure whether 
FPU does matter and whether emulator has FPU support or not.
