Android release: Eclair on TI SDP3430 board
Objective: To integrate the video encoding functionality(H.264 codec)
using proprietary mechanism instead of onboard DSP
Primary code changes: OMX component for video encoding and CameraHal
modified (see below for details)
Files in these directories are modified:
hardware/ti/omx/video/src/openmax_il/video_encode/inc/
hardware/ti/omx/video/src/openmax_il/video_encode/src/
hardware/ti/omap3/camera/
------------------------------------------------------------------------------------------------
Problem Description:
Video camera preview starts. But fails on the author driver
PREPARE command.
Problem details:
From the logs I can see that the preview starts. After that we
try to initialize the camcorder.
[VIDIOC_S_CTRL, VIDIOC_QUERYBUF ioctl's have passed by now, and the
driver ioctl's of VIDIOC_QBUF and VIDIOC_DQBUF are working fine now ]
OMX core gets loaded. After this AuthorDriver will report the below
commands and its status:
AUTHOR_INIT PVMFSuccess
AUTHOR_SET_VIDEO_SOURCE PVMFSuccess
AUTHOR_SET_OUTPUT_FORMAT PVMFSuccess
AUTHOR_SET_VIDEO_ENCODER PVMFSuccess (H263 is set)
>From the log, now OMX_Core loads the OMX.TI.Video.encoder component
(which is what I have replaced)
Following the Set/Get parameter invocations happen from CameraHal, and
below are their results:
SetParameter:OMX_IndexParamStandardComponentRole exit status = 0
GetParameter :OMX_IndexParamVideoInit -do-
GetParameter:OMX_IndexParamPortDefinition -do-
GetParameter:OMX_IndexParamPortDefinition -do-
GetParameter:OMX_IndexParamVideoPortFormat -do-
CameraService log shows the camera is now in preview mode, and the
preview frames are coming from the driver (can be seen in the LCD)
In the Author driver, I can see that some component has issued a
PREPARE command. CommandCompleted(const PVCmdResponse&aResponse) in
the Author driver is invoked, which reports that error is: -15. From
the Packet Video framework, this error code refers to
PVMFErrNoResources. This is the place where I am not getting the clear
flow and request for your
help.
Now, to debug I had some debug messages in below packet video files:
a) external/opencore/engines/2way/src/pv_2way_engine.cpp
b) external/opencore/nodes/pvomxencnode/src/pvmf_omx_enc_node.cpp
My debug messages arent coming from the PVMF. So I want to understand
the flow between the OMX, packet video and authordriver. That will
help me know, who has set the error value to PVMFErrNoResources and
invoked the AuthorDriver::CommandCompleted().
