问题
Kindly execuse me for the bit longer description about the problem.
I have a custom board with DM3730 processor, and building android rowboat from
http://code.google.com/p/rowboat/wiki/JellybeanOnBeagleboard_WithSGX
OBJECTIVE: ENABLING HARDWARE DECODER.
2.1) For that, I need OMAX-IL Interface. Hence looked at the source code downloaded from TI. But i do not find omap3/ directory under hardware/ti/ which represents OMX implementation.
2.2) Hence downloaded from AOSP Jelly Bean Code By:
git clone https://android.googlesource.com/platform/hardware/ti/omap3 -b jb-release
2.3) According to https://source.android.com/devices/media.html
* I could build libstagefrighthw.so, libOMX_Core.so, OMX.TI.Video.Decoder.so [ ofcourse with commenting some error lines..]
2.4) Changed media_codec.xml to keep the below entry:
<MediaCodec name="OMX.TI.Video.Decoder" type="video/avc"/>
2.5) Built the DSP according to [ Note: i took latest ] IE: DVSDK
http://code.google.com/p/rowboat/wiki/DSP#Instruction_Difference_for_Build_and_Run_Froyo+DSP
Instead of
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/4_01_00_09/index_FDS.html
took new version of dvsdk from below link;
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_4_00/latest/index_FDS.html
First think, would like to confirm if it is the right approach? or what other underpinnings that i need to be aware of ?
Where I Struck?
1) DSP Layer generates two device files /dev/dsplink and /dev/cmem.
whereas the dspbridge in omap3/ tries to communicate with /dev/DspBridge.
Hence i created symbolic link to /dev/DspBridge to /dev/dsplink.
2) Found the below Flow right from the framework.
1) OMXMaster Loads libstagefrighthw.so, and get the Plugin Instance.
2) Plugin Instance loads libOMX_Core.so.
3) Now the Component libOMX.TI.Video.Decode is detected,
3) I tried two things:
3.1) Getting into gallery: I got into the below issue while accessing album.

I tried with #dspexec -v
Having looked at the code of libdspbridge, it opens the device file /dev/dsplink, and emumerates the device [ i am not sure what it is doing], but emumeration fails because of sending ioctl to the device.
http://androidxref.com/4.1.1/xref/hardware/ti/omap3/dspbridge/libbridge/dsptrap.c
DSPTRAP_Trap returns dwResult as -1 .
Kindly point out where my issue is?
UPDATE:
Finding:
1) dsp-bridge, dsp-link both drivers are different, and the DSP which is built for dsp-link, and i am trying with dsp-bridge.
回答1:
Certainly the error is caused by your having linked /dev/dsplink to /dev/DspBridge. Dsplink is the wrong driver to use in this case. You'll need to build DspBridge from the staging area of your kernel, add hooks to load the driver in init.rc with the correct baseimage.dof file, and try again.
