I have started to modify IMSDroid to support CIF video size. Perhaps I don't 
have all information about your network architecture because all responses sent 
from your client don't respect the specifications (RFC 3264 and 
draft-ietf-sipping-sip-offeranswer-12).

1. H263
  - IMSDroid offers H.263 (34) with QCIF=2
  - The response sent from your contains H.263(34) with QCIF=1;CIF=1, ... and H.263+ (96).
  ==> MUST not add new codec in it's offer
2. H.263+
  - IMSDroid offers H.263+(103) with CIF=2;QCIF=2
  - The response sent from your client contains H263+(96) and H263(34)
  ==> Two errors: MUST not add H263 and the payload type of H.263+ is incorrect
3. H264
  - IMSDroid offers H264 Base Profile 1.0 (104)
  - The response sent from your client contains H264 (96) with a profile-level-id=42000d
  ==> Two errors: The payload type is incorrect and the level does not match.

Do you have any idea why all responses are incorrect?

The latest version (1.0.234) should allow decoding any video size. Tests have 
been done with Eyebeam. 
For encoding size, you can now choose the preferred size. For more info:

Thanks for the update. Will try it.
In the meantime, can you help figure out why the webcam not working on my HTC 
EVO? I looked at logs and it complains about "Invalid picture size requested: 
352x288".

This is very strange as the previous version only support QCIF (176x144) 
encoding (Bandwidth level was useless). As you have eclipse the best way is to 
run the application in debug mode and set a breakpoint in the prepare() 
function (VideoProducer.java) to see which size is requested by the native 
function. You can also change the bandwidth level (low<->medium) to switch from 
QCIF<->CIF to see if the problem persist.
Have you managed to get it to work with another SIP phone?

Original comment by boss...@yahoo.fr on 9 Aug 2010 at 5:31

GoogleCodeExporter commented 8 years ago 
No sorry I confused you. I was using the latest version of your code to test 
with the bandwidth level set to high.
I also ran test calls to Bria and IMSDroid. The logs say it is failing at the 
setParameters() method when it is trying to open the default webcam.

08-09 14:24:21.783: DEBUG/QualcommCameraHardware(65): requested preview size 
768 x 432
08-09 14:24:21.783: DEBUG/QualcommCameraHardware(65): requested picture size 
352 x 288
08-09 14:24:21.783: ERROR/QualcommCameraHardware(65): Invalid picture size 
requested: 352x288

android::QualcommCameraHardware::set
Parameters(const android::CameraParameters&): 2945, rc = -22

I changed the setPictureSize() method in VideoProducer.java to 1024 x 768, then 
it was able to open the webcam and got video to going. But the call would only 
last for 10 secs or so and IMSDroid then crashed.

It's normal to crash. You should also change the frame allocation size.
From: float capacity = (float)(width*height)*1.5f/* (3/2) */;
To: float capacity = (float)(1024*768)*1.5f/* (3/2) */;

Original comment by boss...@yahoo.fr on 9 Aug 2010 at 8:53

GoogleCodeExporter commented 8 years ago 
That fixed the 30 secs in-call crash. Now it is crashing during call hang up.
Also, heavy delay is occurring on the inbound video shown on the screen. Looks 
like 1024x768 is a bit too much? Do you know how to set the picture size to CIF 
without the Android platform complaining about invalid picture size?

Original comment by whg...@gmail.com on 9 Aug 2010 at 10:01

GoogleCodeExporter commented 8 years ago 
I confirm that 1024x768 is Toooo much for a mobile. You have the delay because 
the CPU overhead. You should only have delay when you start sending video. Is 
it right?
I'm looking into android source code to understand why this fail. According to 
your log the camera supports CIF (see line 243).
You can also use adb tool to see the "CPU usage".

I printed the webcam parameters out:
preview-size-values=1280x720,800x480,768x432,720x480,640x480,576x432,480x320,400
x240,384x288,352x288,320x240,272x272,240x240,240x160,176x144;
picture-size-values=3264x2448,3264x1952,2592x1952,2592x1552,2048x1536,2048x1216,
1600x1200,1280x960,1280x768,1024x768,640x480,640x384,512x384,400x400,272x272;
Now I am testing some of these combinations.

I tested with Bria and my initial finding is that everytime there will be some 
delay no matter what. I used setPreviewSize(176, 144), setPictureSize(272 , 
272) and bandwidth set to low for my testing.

Which SIP client you have tested with that gave you the least delay and best 
performance?

GoogleCodeExporter commented 8 years ago 
Very strange. I have done my tests with linphone, eyeabeam, xlite and ekiga.
The delay is on the remote or local video?
Which codec are you using? Do you have the same issue with all codecs?
What is the average CPU usage (with and without outgoing video)?

Perhaps you can tell me the setup you got when you tested it on your HTC HERO 
with EyeBeam? Did you have to change the code to set the 272x272 picture size? 
I used a Sprint HTC HERO.

Original comment by whg...@gmail.com on 10 Aug 2010 at 8:43

GoogleCodeExporter commented 8 years ago 
you don't need to change the picture size. QCIF is already supported by Hero.
Try the test with QCIF and tell me what is the result?
According to Android source code, all devices should support QCIF and CIF. The 
problem with EVO is very strange. Video resizing (FFMpeg swscale()) is one of 
the function which use most CPU cycles.

The function to comment is from VideoProducer.java.

I tried imsdroid-1.0.234.apk on the HTC Hero. I set bandwidth to low, which 
means QCIF. I also disabled full-screen. When I tested it with EyeBeam, I got 
only one-way video because it complained about "Invalid picture size requested: 
176x144" when I did "Send Video". How did you get it to work without changing 
the picture size? I am lost here.

In the comments 22 and 26: I said "HTC Hero" and not "HTC EVO". 
It was about CPU usage. You cannot consume more CPU on EVO(1GHz) than 
Hero(528Hz). Even on an old G1 H.263 call does take 66%. Only H.263 and Theora 
should take more than 50%.

No but whglee is on the right direction. He has found that the problem come 
from the requested picture sizes (QCIF or CIF) which are not supported by HTC 
EVO. The problem could be resolved with getSupportedPictureSizes() function 
(http://developer.android.com/reference/android/hardware/Camera.Parameters.html#
getSupportedPictureSizes%28%29) available starting API level 5.

you need Android SDK tools (adb, ddms) installed on your development machine to 
capture those logs from the EVO.

do you mind to run a logcat from your Hero when making a video call? I would 
like to compare the webcam params on Android 1.5 against my Android 2.1 Hero.
thanks.

GoogleCodeExporter commented 8 years ago 
See attached.
As I said in comment 34. If you are targeting Android 2.0 or later you can use 
getSupportedPictureSizes() to get supported sizes. Another possible 
optimization is to check if your camera support YUV40SP. If yes, this will 
avoid to convert the picture from NV21 before encoding ().
On Android 2.0 and later you have many possibilities (AMR Cortex, 
CallbackBuffer, Picture Format, ...) to optimize the encoding process.
In all cases, H.263 should not take 66%.

I found out why there is a delay on the inbound video everytime I added the 
outgoing video leg. It was the build target. IMSDroid built on API level 3 
(Android 1.5) will not have the delay problem. If it is built on API level 7 or 
8 (Android 2.1 or 2.2), I will see delay. Looks like those optimization you 
mentioned are needed for Android 2.2 and later.

Also, if I set the bandwidth to high, I will see heavy delay on the inbound 
video when outbound video is on.

Regarding picture size, getSupportedPictureSizes() must be used to determine 
the supported size for a given device and IMSDroid can set it accordingly. The 
HTC Hero (2.1) and EVO (2.2) I have don't offer standard QCIF or CIF picture 
size. But, I can use whatever available size returned from the get size method 
and it works for me.

Original comment by whg...@gmail.com on 11 Aug 2010 at 9:24

GoogleCodeExporter commented 8 years ago 
The problem is that getSupportedPictureSizes() is only supported starting API 
level 5 while we target API Level 3 and later.
Have you tried to use 
addCallBackBuffer(http://developer.android.com/reference/android/hardware/Camera
.html#addCallbackBuffer%28byte[]%29) instead of onPreviewFrame()?

Could you tell if it works for you?

Original comment by boss...@yahoo.fr on 12 Aug 2010 at 7:47

GoogleCodeExporter commented 8 years ago 
No you only need it for the Producer. It will allow you to use a single buffer 
instead of a buffer-per-frame. The problem with onPreviewFrame is that it will 
create, marshal and destroy a buffer for each _data[] callback. If you look at 
the log you will see a lot of messages about the GC.
addCallbackBuffer is used in conjunction with setPreviewCallbackWithBuffer. 
Each time you provide the buffer the callback should be called when the buffer 
is full.

can you explain what onPreviewFrame() does for VideoProducer? Looks like it is

If I use addCallbackBuffer and setPreviewCallbackWithBuffer, whatever code in

buffers would you recommend?

I got the addCallbackBuffer and setPreviewCallbackWithBuffer to work on calls 
with video working both ways. But the delay on the inbound video stream using 
CIF is still horrible. QCIF works great. I am testing it with Bria and only 
H.263 codec enabled. Please take a look at the attached file and let me know if 
I am doing it correctly. I just can't believe HTC EVO, with all that CPU speed, 
cannot support 2 way CIF video calls.
