[FFmpeg-devel] [PATCH] avcodec/apedec: fix prediction

2022-06-30 Thread Zhao Zhili
From: Zhao Zhili Fixes ticket #9816. Regression since ed0001482a74b60f3d5bc5. Prediction value larger than INT32_MAX should be treated as negative. The code already depends on undefined right shift behavior before the patch, which doesn't get fixed by the patch. Signed-off-by: Zhao Zhili ---
