Until the codec signals INFO_OUTPUT_FORMAT_CHANGED, MediaCodec returns the output format set up at configure time. The decoder parsed that format right after start() and copied its crop rectangle, display size and color description into the codec context, although at that point the codec has not decoded anything and these fields hold its defaults. For a 1920x1080 HLG stream, c2.xring.hevc.decoder reports the crop rectangle Rect(0, 0, 175, 143) and BT.601 SDR color there, and MediaTek decoders report rectangles such as Rect(0, 0, 318, 238). Callers reading the codec context after avcodec_open2() got 176x144 or 319x239 and a wrong color description instead of the stream properties. Keep the values set by the caller until the codec signals a format change. The pixel format is still taken from the initial format, as it reflects the configuration. If the first output buffer arrives without a format change, the initial format describes the decoded frames and is applied at that point.
