在Jelly bean中启用硬件编码器4.1.1划艇DM3730

Question

请好好执行一下我对这个问题的描述。

我有DM3730处理器定制电路板，并从

http://code.google.com/p/rowboat/wiki/JellybeanOnBeagleboard_WithSGX 

目的建立的Android划艇：能够提供硬件解码器。

2.1）为此，我需要OMAX-IL接口。因此查看了从TI下载的源代码。但我没有找到代表OMX实现的omap3/目录下的hardware/ti/。

2.2），因此，从AOSP果冻豆代码下载到：

git clone https://android.googlesource.com/platform/hardware/ti/omap3 -b jb-release 

2.3）根据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）变更media_codec.xml保持以下条目：

<MediaCodec name="OMX.TI.Video.Decoder" type="video/avc"/> 

2.5）建立了DSP协议荷兰国际集团为[注：我花了最新] 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 

首先想到的，想确认是否是正确的做法？或 我需要注意哪些其他基础？

我在哪里碰到？

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.

我试着用#dspexec -v

说完看着libdspbridge的代码，它会打开设备文件/ dev/DSPLINK和emumerates设备[我不知道它是做什么] ， 但由于将ioctl发送到设备，因此emumeration失败。

http://androidxref.com/4.1.1/xref/hardware/ti/omap3/dspbridge/libbridge/dsptrap.c

DSPTRAP_Trap返回dwResult为-1。

请指出我的问题在哪里？

UPDATE：

发现：

1）DSP桥，DSP链接两位车手是不同的，这是DSP链接建立的DSP，以及我与DSP努力-桥。

Answer 1

当然，这个错误是由你将/ dev/dsplink链接到/ dev/DspBridge引起的。在这种情况下，Dsplink是错误的驱动程序。您需要从内核的临时区域构建DspBridge，添加挂钩以使用正确的baseimage.dof文件在init.rc中加载​​驱动程序，然后重试。
