avcodec/mediacodecdec: warn when input buffers are not configured with proper size
In rare circumstances, if the codec is not configured with the
proper parameters the input buffers can be allocated with a size
that's too small to hold an individual packet. Since MediaCodec
expects exactly one incoming buffer with a given PTS, it is not
valid to split data for a given PTS across two input buffers.
See https://developer.android.com/reference/android/media/MediaCodec#data-processing:
> Do not submit multiple input buffers with the same timestamp
