Ice not found in Baresip WebRTC Demo on openwrt and MIPS.

[Ismael Bonato]

Hello,

I'm working on porting webRTC demo to Mediatec MIPS architecture using OpenWRT, I've write a new makefile and it compiles, but when I run the executable it has these errors.

root@OpenWrt:/# baresip-webrtc  
Local network address:  IPv4=wlan0|192.168.1.1  
dtls_srtp: failed to enable SRTP profile (Function not implemented)
module dtls_srtp.so: Function not implemented

dl: mod: /usr/lib/baresip/modules/v4l2.so (Error loading shared library /usr/lib/baresip/modules/v4l)

ausrc: alsa
auplay: alsa
demo: medianat 'ice' not found

I'm struggle to understand why the demo cannot find the ice module?

I've updated baresip to the newer version 1.0.0 in the openwrt repository

https://github.com/openwrt/telephony/tree/openwrt-21.02/net/baresip

My Makefile is simple as you can see.

TARGET:=baresip-webrtc

SOURCES:=\
    src/demo.c \
    src/session.c \
    src/main.c \
    src/util.c

OBJECTS:=\
    demo.o \
    session.o \
    main.o \
    util.o

#CFLAGS  := -I$(TARGET_DIR)/usr/include/
#CFLAGS  += -I$(TARGET_DIR)/usr/include/re/
#CFLAGS  += -I$(TARGET_DIR)/usr/include/gpiohal/
#LDFLAGS += -L$(TOOLCHAIN_DIR)/usr/lib -L$(TOOLCHAIN_DIR)/lib
#LDFLAGS += -L$(TARGET_DIR)/usr/lib/ -L$(TARGET_DIR)/lib/
LDFLAGS += -lbaresip -lre -lrem
#LDFLAGS += -L.

all: build $(TARGET)

build:
    $(CC) $(CFLAGS) $(LDFLAGS) -fPIC $(SOURCES) -c

$(TARGET):
    $(CC) $(CFLAGS) $(LDFLAGS) $(OBJECTS) src/main.c -o $(TARGET)

clean:
    rm *.o $(TARGET)

Best regards.

hi,

have you tested this on a regular host system first,
such as OSX or Linux ?


you should check the first error, and then fix that first.


which version of OpenSSL are you using ?


make sure re is compiled with this flag enabled:

USE_OPENSSL_SRTP

Hi,

We are using OpenSSL version 1.0.2s on Openwrt and on ubuntu 18.04 we are using version 1.1.1.

I'm going to try to use this flag.

Thank you very much.
