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
