Hi, I'm having a hard time getting speex to work on Windows Mobile. I'm using version 1.0.3. I had been using only G.711, with the following configuration in config_site.h: #define PJ_HAS_TCP 0 #define PJSIP_HAS_TLS_TRANSPORT 0 #define PJMEDIA_HAS_SPEEX_AEC 0 #define PJMEDIA_ECHO_SUPPRESS_FACTOR 1 #define PJMEDIA_CODEC_MAX_SILENCE_PERIOD 0 #define PJMEDIA_HAS_STEVEU_PLC 0 #define PJMEDIA_HAS_G711_PLC 0 #define PJMEDIA_HAS_SMALL_FILTER 0 #define PJMEDIA_HAS_LARGE_FILTER 0 #define PJMEDIA_HAS_G711_CODEC 1 #define PJMEDIA_HAS_SPEEX_CODEC 0 #define PJMEDIA_HAS_GSM_CODEC 0 #define PJMEDIA_HAS_ILBC_CODEC 0 #define PJMEDIA_HAS_L16_CODEC 0 #define PJMEDIA_HAS_SRTP 0 #define PJMEDIA_SOUND_IMPLEMENTATION PJMEDIA_SOUND_WIN32_MME_SOUND #define PJMEDIA_PREFER_DIRECT_SOUND 0 #define PJMEDIA_SND_DEFAULT_REC_LATENCY 100 #define PJMEDIA_SND_DEFAULT_PLAY_LATENCY 100 #define PJMEDIA_SOUND_USE_DELAYBUF 0 #define PJMEDIA_SOUND_BUFFER_COUNT 20 This has been working fine with G.711. I then wanted to add SPEEX, so I changed PJMEDIA_HAS_SPEEX_CODEC in the above to 1. Running this, the program would hang when media was activated for a SPEEX call, but still worked for a G.711 call. I then found a recommended WINCE config in config_site_sample.h, which I tried: #define PJ_HAS_FLOATING_POINT 0 #define PJMEDIA_HAS_G711_PLC 0 #define PJMEDIA_HAS_L16_CODEC 0 #define PJMEDIA_HAS_SPEEX_AEC 0 #undef PJMEDIA_RESAMPLE_IMP #define PJMEDIA_RESAMPLE_IMP PJMEDIA_RESAMPLE_LIBRESAMPLE #define PJMEDIA_WSOLA_IMP PJMEDIA_WSOLA_IMP_WSOLA_LITE #define PJSUA_DEFAULT_CODEC_QUALITY 5 #define PJMEDIA_CODEC_SPEEX_DEFAULT_QUALITY 5 #define PJMEDIA_SDP_NEG_PREFER_REMOTE_CODEC_ORDER 0 With this config, the program would not hang, but there was no sound in or out, for any call, SPEEX or G.711. I also discovered in the log that the sound device was giving "Unanticipated host error"s during initialization, and that no sound device could be opened. I compared this log to the original configuration and found that this log was using PortAudio while the original was using WMME. This configuration also left the microphone in a broken state. If after exiting the program I started a program built with my original config, the mic would not work. I would have to reboot the device, after which the mic worked again with my original config program. So I added to the recommended WINCE config the following: #define PJMEDIA_SOUND_IMPLEMENTATION PJMEDIA_SOUND_WIN32_MME_SOUND #define PJMEDIA_PREFER_DIRECT_SOUND 0 #define PJMEDIA_SND_DEFAULT_REC_LATENCY 100 #define PJMEDIA_SND_DEFAULT_PLAY_LATENCY 100 #define PJMEDIA_SOUND_USE_DELAYBUF 0 #define PJMEDIA_SOUND_BUFFER_COUNT 20 Running with this config, the program hung again, when a speex call was made or received. A G.711 call still worked. I'm out of ideas. Unless it absolutely can not be made to work with 1.0.3, I really must stay with that version (instead of going for 1.5.5). I've been told that SPEEX works for Windows Mobile. Can someone please tell me what is needed to get it to work?
