I mean "camera hal from vendor". You can check the camera hal's position in the following diagaram. https://github.com/sotaroikeda/firefox-diagrams/blob/master/dom/dom_camera_FirefoxOS_1_1.pdf?raw=true
The following is a link to another diagrams. https://github.com/sotaroikeda/firefox-diagrams/wiki/Firefox-Diagrams I re-read your log. From the following, android media server seems crashed because of segmentation fault after CameraHardware::inPreviewThread() was called. At first, you might better to analyze it like using GDB. > W/CameraHardware( 409): int android::CameraHardware::inPreviewThread(): > return from wait > F/libc ( 409): Fatal signal 11 (SIGSEGV) at 0x40fc0c00 (code=1) > I/DEBUG ( 75): *** *** *** *** *** *** *** *** *** *** *** *** *** *** > *** *** > I/DEBUG ( 75): Build fingerprint: 'unknown' > I/DEBUG ( 75): pid: 409, tid: 497 >>> /system/bin/mediaserver <<< > I/DEBUG ( 75): signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr > 40fc0c00 sotaro ----- Original Message ----- From: [email protected] To: [email protected] Sent: Thursday, November 28, 2013 10:57:22 PM Subject: Re: [b2g] Ascend G300 - camera not working and scaling UI Hi Sotaro Ikeda, Sorry, I'm not really understand. What do mean by saying "android camera hal"? Is that libcamera_client and libcameraservice of Android or lib camera hal from vendor? Could you more clarify on this too :"the USB Webcam seems not support android camera hal" Many thanks.
