Camera error: Can't cnnect to the camera

jiejia — Wed, 31 May 2017 07:03:01 GMT

Dear all,

board: refer to mx6q-sabresd

BSP:android_M6.0.1_2.0.0

I have a camera(1920*1080 30fps yuv422) conneted to my board of csi0. I had finish the camera driver, and I had wrote my hal according to Ov5640Csi.cpp in libcamera3. When I used the camera app released by system, it can be preview and taken picture. When I used the camera app to record, a dialog box was pop up:

Camera error

Can't cnnect to the camera

I think the problem my be the hal file. Here is my hal file. Any advises are appreciated.

Gv7601Csi.cpp:

#include "Gv7601Csi.h"

Hello Jie,

You should modify parameters to be your camera's in media_profiles.xml.

try it, please!

Hi, Sun

Thanks for reply. I have tried changed media_profiles.xml to support only 1080P, the error is the same.

<?xml version="1.0" encoding="utf-8"?>
<MediaSettings>

<CamcorderProfiles cameraId="0">
<EncoderProfile quality="1080p" fileFormat="mp4" duration="30">
<Video codec="h264"
bitRate="8000000"
width="1920"
height="1080"
frameRate="30" />

<VideoEncoderCap name="h263" enabled="true"
minBitRate="48000" maxBitRate="8000000"
minFrameWidth="176" maxFrameWidth="1920"
minFrameHeight="144" maxFrameHeight="1080"
minFrameRate="1" maxFrameRate="30" />

There is on sound card in my board. We only nedd to record the image. Would my problem be caused by the audio record?

Here is the log:
