First, add some formatting
Take the RMVB format as an example, due to the lisence problem, a rmvb format video file is copied to the phone's SD card, the file cannot be displayed as a video file, if your company has a third-party apk to support playback of the format of the video, you can follow the methods below to add support for the RMVB format.
In Frameworks\base\media\java\android\media\mediafile.java: About 270 rows, add the mimetype in RMVB format:
Addfiletype ("AVI", File_type_avi, "Video/avi");
Addfiletype ("MOV", File_type_quicktime_video, "video/quicktime");
Addfiletype ("QT", File_type_quicktime_video, "video/quicktime");
Addfiletype ("RMVB", FILE_TYPE_RMVB, "Video/x-pn-realvideo");//Add RMVB
Then compile the Framework/base module, push the generated Framework.jar and Secondary-framework.jar to the phone, and then restart the phone:
ADB push Framework.jar System/framework
ADB push Secondary-framework.jar System/framework
ADB reboot
Ii. cancellation of a format
In the case of wma/wmv format, if you want to cancel support for this format, you can modify it as follows:
The first step in the format of the MIME type is originally video\audio to unknown
Modify Frameworks\base\media\java\android\media\mediafile.java
Addfiletype ("WMV", file_type_wmv, "video/x-ms-wmv", mtpconstants.format_wmv);
Addfiletype ("ASF", file_type_asf, "video/x-ms-asf");
Addfiletype ("WMA", File_type_wma, "audio/x-ms-wma", mtpconstants.format_wma);
If you want to completely remove the corresponding video codec, you can proceed to the second to third step.
The second step is to find out if the following files have macros Mtk_asf_playback_support (JB2,JB3,JB5) or Mtk_wmv_playback_support and Mtk_wma_playback_support (JB9,KK)
Alps\mediatek\config\project name\projectconfig.mk
Alps\mediatek\config\platform name\projectconfig.mk
Alps\mediatek\config\commone\projectconfig.mk
If so,
Please place the mtk_asf_playback_support as no;
Please place the mtk_wmv_playback_support as no;
Please place the mtk_wma_playback_support as no;
Step three Modify the Media_codecs.xml file
Mediatek\config\common\media_codecs.xml
Mediatek\config\platform Name\media_codec.xml
Remove:
<mediacodec name= "OMX. Mtk. VIDEO. DECODER. VC1 "type=" video/x-ms-wmv ">
<mediacodec name= "OMX. Mtk. AUDIO. DECODER. WMA "type=" audio/x-ms-wma "/>
Android adds or cancels support for a certain media file format
