Не помогло. Ошибка идёт отсюда: ocv.comp.FFMSource sws_getCachedContext(nil, pCodecCtx^.Width, pCodecCtx^.Height, pCodecCtx^.pix_fmt, pCodecCtx^.Width, pCodecCtx^.Height, AV_PIX_FMT_BGR24, SWS_BILINEAR, nil, nil, nil) возвращает nil Дебаггер показывает, что pCodecCtx^.Width = 0, pCodecCtx^.Height = 352, pCodecCtx^.pix_fmt = AV_PIX_FMT_YUVJ420P

Вылечилось перезагрузкой всех dll и полной пересборкой библиотеки
