Speex on Nokia Symbian S60 phones

Folks -- I am attempting to retrieve a new certificate on a Puppet client whose certificate was revoked on the Puppet master. The original certificate was revoked using the command: # puppet cert --revoke el5-puptest-2.localdomain I have deleted the /var/lib/puppet/ssl directory on the client, and issued the following command: # puppet agent --test --waitforcert=20 This produces the

size of speex packets when VAD/CNG is enabled
Hi all, supposing to have speex working at 3.95, when VAD/CNG is employed, which is the size of those "silence" samples respect to voice samples? I am wondering if it could be possible to lower even the transmission of VAD/CNG samples by specifying "outbound" in the communication channel only 1 bit instead of sending the whole VAD/CNG packet. I am doing the same for AMR

Palm OS port
hello all, At my workplace, our colleague Mukesh has just completed a port of speex 1.2.1 to Palm OS. He had to write a couple of mathlib functions, but the trunk remains unchanged. It works quite well, I was wondering if there will be any interest in this port in the distribution. - farhan

Speex on Nokia Symbian S60 phones
Is speex at this stage a good codec to use for real-time voice transmission over a direct CSD connection between two phones? Does anyone have any experience with using Speex on Nokia phones? If speex is not a good solution for this task, what would you recommend? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Speex realtime encoding/decoding "Real world" usage for Windows Mobile / Symbian device
Dear all, i am currently evaluating which codec to be used for a "very narrowband" voice communication system (using either VoIP either GSM CSD) on mobile devices running Windows Mobile and Symbian OS. I had experience in using AMR-NB 4.75 with VAD on Symbian OS and all worked very well. However, AMR it's not royalty free and if i need to use it on Windows Mobile i will need

Speex realtime encoding/decoding "Real world" usage for Windows Mobile / Symbian device
Hi all, i am not criticizing the technology itself, but the fact that from the point of view of the implementator that need to make a technological choice while selecting a codec to be used for a mobile multimedia application, speex does not provide affordable informations on "supported platform". Without arranging a test bed with a lot of devices and spending a lot of money i
