ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at outlook.com> | Fri Jun 13 00:41:34 2025 +0200| [2583c7abcf2caa1d134c95bd6ebdf6a80f4c1bed] | committer: Andreas Rheinhardt

avcodec/svq1enc: Don't initialize unneeded block_index

The motion estimation code only uses block_index[0..3],
so only initialize that (just like estimate_motion_thread()
in mpegvideo_enc.c).
