[Freeswitch-dev] Recompile mod_opus for 8KHz sampling rate
by Dimosthenis Arkoudeas 05 Aug '13

05 Aug '13

Hi all, Playing with mod_opus came up with the following. I am trying to recompile the codec with 8Khz and 40ms ptime. I am not familiar with the codec internals and not really sure what parameters should I change... In mod_opus.c : Line 59: int bitrate_bps = codec->implementation->bits_per_second; int use_vbr = 1; int complexity = 10; int use_inbandfec = 1; int use_dtx = 1; int bandwidth = OPUS_BANDWIDTH_FULLBAND; int err; I suppose that the bandwidth must be changed to OPUS_BANDWIDTH_NARROWBAND and use_vbr=0 and I haven't found yet whether the FEC parameter is passed to opus encoder. And in Line 184 , I think the following parameters must be changed switch_codec_interface_t *codec_interface; int samples = 480; int bytes = 960; int mss = 10000; int x = 0; int rate = 48000; int bits = 32000; Can you propose any values about these parameters to achieve 8khz with 40ms packet time? Thanks for any help, Dimosthenis

[Freeswitch-dev] SSL_read in do_dtls() question
by Iwan Budi Kusnanto 26 Jul '13

26 Jul '13

Hi, Just curious, why use SSL_read in do_dtls() [1] while in the same time Freeswitch use BIO_write. Just wondering why not use BIO_read. I replaced SSL_read with BIO_read and it is working fine with chrome for few calls. Not intensive test actually. So, the line become if (BIO_read(dtls->write_bio, dtls->data, dtls->bytes) == (int)dtls->bytes) Another question, still in do_dtls() about this line: BIO_write(dtls->read_bio, dtls->data, dtls->bytes) Why use dtls->read_bio in write operation? Why also need dtls->write_bio in my BIO_read above. It seems weird for me [1]https://github.com/FreeSWITCH/FreeSWITCH/blob/master/src/switch_rtp.c#L23… -- Iwan Budi Kusnanto
