Subject: [PATCH v2] avcodec/mediacodecdec: call MediaCodec.stop on close
Usually the MediaCodec context will be released immediately, or it
binutils 2.43 has stricter validation for labels[1] and results in errors
when building ffmpeg for armv5:
src/libavcodec/arm/mlpdsp_armv5te.S:232: Error: junk at end of line, first
unrecognized character is `0'
Remove the leading zero in the "01" label to resolve this error.

In vtenc_populate_extradata, supported_props should always be released
to avoid memory leak.

Hardware frames with RGB colorspace will not have a YCbCrMatrixKey.
Currently, it will spam the console with warning if rgb frame is
uploaded.
