Hi all. I’ve looked for topic about installation of codecs. I’d like to know where I can find codecs to download and how I install it. Thanks.
What is your goal exactly? Is there a specific codec you are looking for? The Asterisk installation process (make && make install ) will install all of the commonly used codecs. g711u, g711a, gsm, etc… Please try to be more specific with your question.
In fact, I’m not sure which codecs my asterisk have installed. I tried use a ATA with G723 but it return me a error messenge that I don’t remember. Probably it isn’t installed, or not configured. I’m newer in this world. How can I know which codecs I have installed and where can I find G723, if it isn’t installed? Thanks!
Open the asterisk console. (asterisk -vvvvgc or asterisk -r if asterisk is already running in background ). Type ‘show codecs’. That should print this list below. As far as I understand this is pretty standard across Asterisk.
INT BINARY HEX TYPE NAME DESC
1 (1 << 0) (0x1) audio g723 (G.723.1) 2 (1 << 1) (0x2) audio gsm (GSM) 4 (1 << 2) (0x4) audio ulaw (G.711 u-law) 8 (1 << 3) (0x8) audio alaw (G.711 A-law) 16 (1 << 4) (0x10) audio g726 (G.726) 32 (1 << 5) (0x20) audio adpcm (ADPCM) 64 (1 << 6) (0x40) audio slin (16 bit Signed Linear PCM) 128 (1 << 7) (0x80) audio lpc10 (LPC10) 256 (1 << 8) (0x100) audio g729 (G.729A) 512 (1 << 9) (0x200) audio speex (SpeeX) 1024 (1 << 10) (0x400) audio ilbc (iLBC) 65536 (1 << 16) (0x10000) image jpeg (JPEG image) 131072 (1 << 17) (0x20000) image png (PNG image) 262144 (1 << 18) (0x40000) video h261 (H.261 Video) 524288 (1 << 19) (0x80000) video h263 (H.263 Video) 1048576 (1 << 20) (0x100000) video h263p (H.263+ Video)
Perhaps if you describe your setup and what you are trying to do a little more in depth, someone on the list can help you more.
I’d like to use the g722 codec with Asterisk. Has someone already used it? Is there a project about it ?
Thanks for all usefull contribution.
You can have a try on G.722 codec from www.imtelephone.com . It is totally free for evaluation version and it is very easy to use.
