Jelly bean 4.1.1 rowboat에서 하드웨어 인코더 활성화 DM3730

Question

문제에 대한 자세한 설명은 친절하게 알려주십시오.

나는 DM3730 프로세서와 맞춤형 보드를 가지고 있고,

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

목적에서 안드로이드 노 젓는 보트를 구축 : 하드웨어 디코더를 가능하게.

2.1)이를 위해 OMAX-IL 인터페이스가 필요합니다. 따라서 TI에서 다운로드 한 소스 코드를 살펴 보았다. 그러나 나는 OMAP 구현을 나타내는 하드웨어/ti/하에 omap3/ 디렉토리를 찾지 못했습니다. 따라서 의해 AOSP 젤리 코드에서 다운로드

2.2) : 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)에 따르면

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

2.3) 아래의 항목을 유지하기 위해 media_codec.xml을 변경 :

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

2.5) DSP 협정 에 보내고 [참고 : 나는 최신했다] 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 

먼저 생각을, 그것은 올바른 접근 방식 인 경우 확인 하시겠습니까? 또는 내가 알고 있어야하는 다른 기초 사항은 무엇입니까?

나는 어디에서?

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.

내가 libdspbridge의 코드를 보았다면서 #dspexec -v

과 노력, 디바이스 파일은/dev/DSPLink를를 열고 장치를 [나는 그것이 무엇을하고 있는지 잘 모르겠습니다] emumerates , 장치에 ioctl을 보내면 emumeration이 실패합니다.

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

는 DSPTRAP_Trap -1로 dwResult을 반환합니다.

내 문제는 어디에서 지적하고 있습니까?

UPDATE :

찾기 :

1) DSP 브리지, DSP 링크 두 드라이버는 다르며, DSP-링크 내장 된 DSP, 그리고 난 DSP를 시도하고있다 -다리.

Answer 1

확실히/dev/dspBridge에/dev/dsplink를 연결하면 오류가 발생합니다. Dsplink는이 경우에 사용할 잘못된 드라이버입니다. 커널의 스테이징 영역에서 DspBridge를 빌드하고 올바른 baseimage.dof 파일로 init.rc에 드라이버를로드하기위한 후크를 추가 한 다음 다시 시도해야합니다.
