[FFmpeg-devel] [PATCH 16/48] avcodec/rv34: Don't use MpegEncContext.block

[Andreas Rheinhardt <ffmpegagent-at-gmail.com@ffmpeg.org>]

From: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

These decoders only need a single 4x4 block; put it in RV34DecContext.
This is in preparation for removing MpegEncContext.block.
