Hi All I have the following setup: Caller: - Raspberry pi running raspbian with wifi and a USB 2.0 web cam. SDL 2.0. V4L2. ffmpeg 1.2. Null audio device Callee - Android phone -> CSipSimple video version. I want to make a one way video call (ie. from RPi to Android). I set SDL_VIDEODRIVER=dummy for my application on Rpi. It shows me the following: >>> vid dev list 08:38:17.555 pjsua_app.c Video device list: 08:38:17.556 pjsua_app.c 3 device(s) detected: 08:38:17.557 pjsua_app.c -2 SDL renderer [SDL][render] (default renderer device) 08:38:17.558 pjsua_app.c Supported capabilities: format, window, resize, wndflags 08:38:17.559 pjsua_app.c Supported formats: RGBA, RGB24, BGRA, DIB , YUY2, UYVY, YVYU, I420, YV12, I420JPG, I422JPG 08:38:17.560 pjsua_app.c -1 USB2.0 PC CAMERA [v4l2][capture] (default capture device) 08:38:17.561 pjsua_app.c Supported capabilities: format 08:38:17.561 pjsua_app.c Supported formats: YUY2, RGB24 08:38:17.563 pjsua_app.c 0 USB2.0 PC CAMERA [v4l2][capture] 08:38:17.563 pjsua_app.c Supported capabilities: format 08:38:17.565 pjsua_app.c Supported formats: YUY2, RGB24 08:38:17.566 pjsua_app.c 1 Colorbar generator [Colorbar][capture] 08:38:17.567 pjsua_app.c Supported capabilities: format 08:38:17.568 pjsua_app.c Supported formats: YUY2, UYVY, YVYU, RGBA, RGB24, BGRA, YV12, I420, I422, I420JPG, I422JPG 08:38:17.569 pjsua_app.c 2 SDL renderer [SDL][render] 08:38:17.570 pjsua_app.c Supported capabilities: format, window, resize, wndflags 08:38:17.570 pjsua_app.c Supported formats: RGBA, RGB24, BGRA, DIB , YUY2, UYVY, YVYU, I420, YV12, I420JPG, I422JPG So, I believe it is correctly able to detect my webcam. On initiating a video call, I can see the following in traces: 08:32:49.945 APP .....Call 0 state=CONNECTING 08:32:49.949 pjsua_media.c .....Call 0: updating media.. 08:32:49.951 pjsua_aud.c ......Audio channel update.. 08:32:49.954 strm0x73670c .......VAD temporarily disabled 08:32:49.957 strm0x73670c .......Encoder stream started 08:32:49.958 strm0x73670c .......Decoder stream started 08:32:49.960 pjsua_media.c ......Audio updated, stream #0: G722 (sendrecv) 08:32:49.961 pjsua_vid.c ......Video channel update.. 08:32:49.984 vstenc0x73b10c .......Encoder stream started 08:32:49.984 vstdec0x73b10c .......Decoder stream started 08:32:49.986 pjsua_vid.c .......Setting up RX.. 08:32:49.988 pjsua_vid.c ........Creating video window: type=stream, cap_id=-1, rend_id=2 08:32:49.989 vid_port.c .........Opening device SDL renderer [SDL] for render: format=I420, size=352x288 @45000:1001 fps 08:32:49.992 vid_port.c .........Device SDL renderer [SDL] opened: format=I420, size=352x288 @45000:1001 fps 08:32:49.993 pjsua_vid.c .........stream window id 0 created for cap_dev=-1 rend_dev=2 08:32:49.995 pjsua_vid.c .........Window 0 created 08:32:49.997 sdl_dev.c ........Starting sdl video stream 08:32:49.998 pjsua_vid.c .......Setting up TX.. 08:32:49.999 pjsua_vid.c ........Creating video window: type=preview, cap_id=0, rend_id=2 08:32:50.000 vid_port.c .........Opening device USB2.0 PC CAMERA [v4l2] for capture: format=YUY2, size=352x288 @30000:2002 fps 08:32:50.006 vid_port.c .........Device USB2.0 PC CAMERA [v4l2] opened: format=YUY2, size=352x288 @30000:2002 fps 08:32:50.008 vid_port.c .........Opening device SDL renderer [SDL] for render: format=I420, size=352x288 @30000:2002 fps 08:32:50.011 vid_port.c .........Device SDL renderer [SDL] opened: format=I420, size=352x288 @30000:2002 fps 08:32:50.011 pjsua_vid.c .........preview window id 1 created for cap_dev=0 rend_dev=2 08:32:50.012 pjsua_vid.c .........Window 1 created 08:32:50.013 v4l2_dev.c ........Starting v4l2 video stream USB2.0 PC CAMERA 08:32:50.049 vstenc0x73b10c .......Encoder stream paused 08:32:50.050 pjsua_media.c ......Video updated, stream #1: H263-1998 (sendrecv) 08:32:50.051 APP .....Call 0 media 0 [type=audio], status is Active But unfortunately, I see a greyed screen on my android phone. I took wireshark traces and could not see any video stream going out from Rpi on H263. Could anyone point out, if I am missing something basic?
