XML 提供的 google avc codec framerate range 不符合 CTS 預期

解决方案

将以下的值修改一下

c2.android.vp8.decoder 1920x1080   Range值:4-8
OMX.MTK.VIDEO.ENCODER.AVC 0320x0240   Range值:14-30
OMX.MTK.VIDEO.ENCODER.AVC 0720x0480   Range值:11-24
OMX.MTK.VIDEO.ENCODER.AVC 1280x0720   Range值:7-15
OMX.MTK.VIDEO.ENCODER.AVC 1920x1080   Range值:7-15

調整 XML google avc codec framerate range
<MediaCodec name="c2.android.avc.encoder" type="video/avc" update="true">
<Limit name="measured-frame-rate-720x480" range="11-25" />

由於Google codec都是軟件實現且由Google直接維護
MTK只需要依照跑出來的數據填進xml即可
官方指導方針:
https://source.android.com/devices/media/oem.html#2_achievable_frame_rates_for_video_codecs
确保有合入以下两笔patch:
ALPS04979477
ALPS05065973
