逻辑宽高（视频 SPS 指定的）：608 × 1080
实际对齐后 stride：横向 = 640，纵向 = 1088
mali_gralloc_adjust_dimensions: alloc_width=608, alloc_height=1152
gralloc 最终分配的 buffer 是 608 × 1152 = 700416。
这和解码器需要的 stride（640×1088） = 696320 对不上，但我不知道这是否是原因;
还有一部分日志在刚才的日志之前：
CCodec com.example.ledcontroller D setup formats input: AMessage(what = 0x00000000) = {
int32_t height = 1080
int32_t level = 65536
int32_t max-input-size = 2097152
string mime = "video/hevc"
int32_t profile = 1
int32_t width = 608
Rect crop(0, 0, 607, 1079)
}
CCodec com.example.ledcontroller D setup formats output: AMessage(what = 0x00000000) = {
int32_t android._color-format = 2135033992
int32_t android._video-scaling = 1
int32_t rotation-degrees = 0
int32_t color-standard = 1
int32_t color-range = 2
int32_t color-transfer = 3
int32_t sar-height = 1
int32_t sar-width = 1
Rect crop(0, 0, 607, 1079)
int32_t width = 608
int32_t height = 1080
int32_t max-height = 1080
int32_t max-width = 608
string mime = "video/raw"
int32_t android._dataspace = 260
int32_t color-format = 2130708361
}
有打印 包含 crop，，这个像是预设解码器输出的信息？ 意思是 codec 想让解码器输出不包含 padding 的帧？
而解码器最终却输出了包含 padding 的帧到一个不包含 padding 的buffer 中？
虽然和解码器解码出帧应该是没问题的，但是，解码器和安卓视频框架对接以及申请应该还是rk来对接的；
期待能否解答一下？
下图是 的问题现象，exoplayer + textureView ，可以明显看到有小的矩形灰色色块，斜着排布，神奇的是，他不是每个像素行都偏移。
