[FAQ27320] GMS ago项目不支持wma,adpcm,ape,alac等audio codec.MT6761 MT6739

admin

带GMS包的ago项目出于项目配置受限的因素，默认不支持以下audio codec：wma,adpcm,ape,alac
下面以mt6761 ago项目为例来作说明：MTK_GMO_RAM_OPTIMIZE被置为yes，所以对应的media codec xml文件名是带ago的
/android/device/mediatek/mt6761/device.mk

1. 1040 ifneq ($(MTK_BASIC_PACKAGE), yes)
   
2. 1041     ifeq ($(strip $(MTK_AUDIO_CODEC_SUPPORT_TABLET)), yes)
   
3. 1042         ifeq ($(strip $(MTK_WMA_PLAYBACK_SUPPORT)), yes)
   
4. 1043             PRODUCT_COPY_FILES += device/mediatek/mt6761/media_codecs_mediatek_audio_tablet.xml:$(TARGET_COPY_OUT_VENDOR)/etc/media_codecs_mediatek_audio.xml:mtk
   
5. 1044         else
   
6. 1045             PRODUCT_COPY_FILES += device/mediatek/mt6761/media_codecs_mediatek_audio_tablet_no_wma.xml:$(TARGET_COPY_OUT_VENDOR)/etc/media_codecs_mediatek_audio.xml:mtk
   
7. 1046         endif
   
8. 1047     else ifeq ($(strip $(MTK_GMO_RAM_OPTIMIZE)), yes)
   
9. 1048         PRODUCT_COPY_FILES += device/mediatek/mt6761/media_codecs_mediatek_audio_phone_ago.xml:$(TARGET_COPY_OUT_VENDOR)/etc/media_codecs_mediatek_audio.xml:mtk
   
10. 1049     else
    
11. 1050         PRODUCT_COPY_FILES += device/mediatek/mt6761/media_codecs_mediatek_audio_phone.xml:$(TARGET_COPY_OUT_VENDOR)/etc/media_codecs_mediatek_audio.xml:mtk
    
12. 1051     endif
    
13. 1052 else
    
14. 1053     PRODUCT_COPY_FILES += device/mediatek/mt6761/media_codecs_mediatek_audio_basic.xml:$(TARGET_COPY_OUT_VENDOR)/etc/media_codecs_mediatek_audio.xml:mtk

ago对应的配置内容如下：

1. /device/mediatek/mt6761/media_codecs_mediatek_audio_phone_ago.xml
   
2. 79 <Included>
   
3. 80     <Decoders>
   
4. 81         <MediaCodec name="OMX.MTK.AUDIO.DECODER.MP3" type="audio/mpeg" rank="6">
   
5. 82             <Quirk name="decoder-lies-about-number-of-channels" />
   
6. 83             <Quirk name="supports-multiple-frames-per-input-buffer" />
   
7. 84         </MediaCodec>
   
8. 85         <MediaCodec name="OMX.MTK.AUDIO.DECODER.GSM" type="audio/gsm" />
   
9. 86     </Decoders>
   
10. 87 </Included>

而非ago项目，对应的xml文件为如下所示：
/device/mediatek/mt6761/media_codecs_mediatek_audio_phone.xml
