[Asterisk-video] app_h324m questions

[Marcin_Nemeczek at drq.pl]

Hi

Because :
        Disclaimer: this command is for informational purposes only.
        It does not indicate anything about your configuration.

Change in main/frame.c   function    static int show_codecs(int fd, int 
argc, char *argv[])

        if ((argc == 3) || (!strcasecmp(argv[3],"audio"))) {
                found = 1;
                for (i=0;i<14;i++) {
                        snprintf(hex,25,"(0x%x)",1<<i);
                        ast_cli(fd, "%11u (1 << %2d) %10s  audio   %8s 
(%s)\n",1 << i,i,hex,ast_getformatname(1<<i),ast_codec2str(1<<i));
                }
        }


regards
marcin

I still have problems. Digging into the source code I see that this 
patch defines:

#define AST_FORMAT_AMRNB        (1 << 13)

In app_h324m there is:
#ifndef AST_FORMAT_AMR
#define AST_FORMAT_AMR            (1 << 13)

Are these codec definitions are supposed to work together?

Further, "show codecs" does not show AMR although I have applied the AMR 
patch. Any hints?

klaus
