avcodec/mpegvideo_enc: Don't segfault on unorthodox mpeg_quant
The (deprecated) field AVCodecContext.mpeg_quant has no range restriction; MpegEncContext.mpeg_quant is restricted to 0..1. If the former is set, the latter is overwritten with it without checking the range. This can trigger an av_assert2() with the MPEG-4 encoder when writing said field. Fix this by just setting MpegEncContext.mpeg_quant to 1 if AVCodecContext.mpeg_quant is set. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
