[Linphone-developers] HTC I/S(Incredible S) Front Cam ISSUE

[Jim Lu]

Dears,

The Linphone-Android.apk can smoothly execute on HTC-I/S last week.

But there has a problem when we use front cam with H.264.

The root cause was found yeaterday. And I would like to share with 

you here.

1.Development Environment:

OS : Ubuntu 11.04

Sun JDK : 1.6.0_26

Eclipse : Indigo

AND-SDK : 2.3.3

Device : HTC Incredible S(2.3.3)

SIP Svr : Asterisk address@hidden OS 5.4

2.Debug Step

2.1. HTC->Setup->Application->Develop->Check the USB Debug.

2.2. Debug with Device

2.2.1 Ubuntu(PC or Virtual Box 4.0.6)->USB->HTC-I/S(or your Device)

2.2.2 Start ADB to connect to DEVICE through Console

address@hidden cd /home/jimlu/eclipse/android-sdk/plateform-tools

address@hidden ./adb kill-server

address@hidden ./adb devices

* daemon not running. starting it now on port 5037 *

* daemon started successfully *

.....HTC/Device info....

3.Start Debug

3.1.Start Eclipse

3.1.1.Fix Issue(?) 

(1).open src/org.linphone.core.video/AndroidCameraRecord.java

(2).go to line 75 , we'll found ....XDDDDD....

   public synchronized void startPreview() { // FIXME throws exception?

in line 130 , the onSettingCameraParameters will crush when HTC I/S change to Front.

Because the fps is 10.0 in rear , and 7.0 in front. So at the line 125, we'll

got rhe range[0] and range[1] as 7000,7000. This will cause qualcomm throw exception. 

Thus, I change the "fps" to 9.0 and then everything goes will in the HTC I/S.

However,I knew that this is the dirty way to fix the issue...I'm still looking for 

the right way to fix this front-cam issue.

If there has any suggestion, please let me know. Thanks.

Best Regards,

Jim Lu
