GstOmxCamera can not get buffer

which SW release and which HW (board + sensor) are you using?

Hi，Mayank:

    The  os is android 4.0.3  ,gstreamer is 0.10.6 and openmax  is 1.1. the board  is omap4430. I got  the native buffer from  display  ,and  how  to  contact  the native buffer and the  OMX_UseBuffer , how  do  the native buffer   will be passed  to the struct used by OMX_UseBuffer? Thank you.

Please refer to the code in the folder mydroid/hardware/ti/omap4xxx/camera/OMXCameraAdapter

Hi,Mayank!

    I  have  read the code in OMXCameraAdapter  and  set the parameters about the camert .I  have  some questions  .

 First  i find  the omx  change from load to idle state failed  in the gstomx_camera.what should be setup in the camera? 

Second the parameters of gstomx_camera which  i  set  is

  Output Port = {

 nBufferCountActual = 6

nBufferCountMin = 3

 nBufferSize = 663552

cMIMEType = (null)

pNativeRender = 0x0

nBitrate = 0

nFrameWidth = 768

 nFrameHeight = 576

nStride = 4096

 nSliceHeight = 0

 xFramerate = 1638400

eCompressionFormat = OMX_VIDEO_CodingUnused

eColorFormat = 0x15, OMX_COLOR_FormatYUV420SemiPlanar

pNativeWindow = 0x0

 }

The  parameters  of camerahal  is

 *** PRV Width = 768
 *** PRV Height = 576
 *** PRV IMG FMT = 15
 *** PRV portCheck.nBufferSize = 748800
  *** PRV portCheck.nBufferCountMin = 3
  *** PRV portCheck.nBufferCountActual = 6
 ***PRV portCheck.format.video.nStride = 4096

now  most parameters  are same except buffer size. but the buffer size can not setup.

the camerahal  will  dequeue  buffer  from  surfaceflinger  and the parameters is

 stride=4096
 width=800
 height=624
 usage=2818
 pixelformat=256
 nativebuffer=0x1360e44

The  gstomx_camera got the buffer from surfaceflinger  and the parameters are same  too.

but the gstomx_camera have the error : ** (gst-launch-0.10:773): CRITICAL **: g_omx_port_allocate_buffers: assertion `port->buffers[i]' failed.

so excetp the parameters of omx port and buffer, what parameter can i setup  and the flow ?

the files are gstomx_camera log  and camera app.4572.camera app.log

3107.gstomx_camera.log

Please share Ducati logs (/d/remoteproc/omap-rproc.1/trace1) from Android app and gst-omx.

Hi,Mayank

    The files are android camera app  and gstomx_camera   6378.camera_trace1.txt    7827.gstomx_trace1.txt   thank you!

Here is the difference between Android and GST:

Android:

[    147.214] [ERR=468] src/new_sensor_MSP.c:[533]:Sen Read ID: 9600, expected ID:9600
[    184.920] [ERR=958] src/msp_camera_api.c:[1462]:video start Sensor - w:1280 h:960!!!

GST

[    147.214] [ERR=468] src/new_sensor_MSP.c:[533]:Sen Read ID: 9600, expected ID:9600
[    147.699] [ERR=472] src/msp_camera_api.c:[1462]:video start Sensor - w:800 h:600!!!

In case gst-omx, looks like you are setting up a different sensor which is configured to output 800x600. Since preview resolution (1280x720) is bigger than sensor resolution, OMX camera reports an error.

Solutions:

1. Make gst-omx pick the right sensor

2. Try with lower preview resolution

Hi,Mayank

   Hi, the camera preview is ok.but  when  i  use the omx  camera  and encode ,find  the wait_for_state()  is  time out  and  the omx core is wrong state .and the buffer  is ok and do not have  other error message.

   The command is  "gst-launch omx_camera mode=1 device=secondary name=cam cam.src ! queue ! surfaceflingersink cam.vidsrc ! queue ! omx_h264enc profile=8 bitrate=1024000 ! filesink location=/mnt/sdcard/ttt  --gst-debug=omx:5". the log is 2100.putty6.log. 

Thank you!
